xfs: fix double ijoin in xfs_inactive_symlink_rmt()
xfs_inactive_symlink_rmt() does something nasty - it joins an inode
into a transaction it is already joined to. This means the inode can
have multiple log item descriptors attached to the transaction for
it. This breaks teh 1:1 mapping that is supposed to exist
between the log item and log item descriptor.
This results in the log item being processed twice during
transaction commit and CIL formatting, and there are lots of other
potential issues tha arise from double processing of log items in
the transaction commit state machine.
In this case, the inode is already held by the rolling transaction
returned from xfs_defer_finish(), so there's no need to join it
again.
