xfs: split xfs_itruncate_finish
Split the guts of xfs_itruncate_finish that loop over the existing extents
and calls xfs_bunmapi on them into a new helper, xfs_itruncate_externs.
Make xfs_attr_inactive call it directly instead of xfs_itruncate_finish,
which allows to simplify the latter a lot, by only letting it deal with
the data fork. As a result xfs_itruncate_finish is renamed to
xfs_itruncate_data to make its use case more obvious.
Also remove the sync parameter from xfs_itruncate_data, which has been
unessecary since the introduction of the busy extent list in 2002, and
completely dead code since 2003 when the XFS_BMAPI_ASYNC parameter was
made a no-op.
I can't actually see why the xfs_attr_inactive needs to set the transaction
sync, but let's keep this patch simple and without changes in behaviour.
Also avoid passing a useless argument to xfs_isize_check, and make it
private to xfs_inode.c.

- * don't, then we'd end up with garbage in the blocks being freed.
- * As long as we make the new_size permanent before actually
- * freeing any blocks it doesn't matter if they get written to.
- *
- * The callers must signal into us whether or not the size
- * setting here must be synchronous. There are a few cases
- * where it doesn't have to be synchronous. Those cases
- * occur if the file is unlinked and we know the unlink is
- * permanent or if the blocks being truncated are guaranteed
- * to be beyond the inode eof (regardless of the link count)
- * and the eof value is permanent. Both of these cases occur
- * only on wsync-mounted filesystems. In those cases, we're
- * guaranteed that no user will ever see the data in the blocks
- * that are being truncated so the truncate can run async.
- * In the free beyond eof case, the file may wind up with
- * more blocks allocated to it than it needs if we crash
- * and that won't get fixed until the next time the file
- * is re-opened and closed but that's ok as that shouldn't
- * be too many blocks.
- *
- * However, we can't just make all wsync xactions run async
- * because there's one call out of the create path that needs
- * to run sync where it's truncating an existing file to size
- * 0 whose size is > 0.
- *
- * It's probably possible to come up with a test in this

- * cases from the values of the function parameters and the
- * inode state but for sanity's sake, I've decided to let the
- * layers above just tell us. It's simpler to correctly figure
