xfs: xfs_bioerror can die.
Internal buffer write error handling is a mess due to the unnatural
split between xfs_bioerror and xfs_bioerror_relse().
xfs_bwrite() only does sync IO and determines the handler to
call based on b_iodone, so for this caller the only difference
between xfs_bioerror() and xfs_bioerror_release() is the XBF_DONE
flag. We don't care what the XBF_DONE flag state is because we stale
the buffer in both paths - the next buffer lookup will clear
XBF_DONE because XBF_STALE is set. Hence we can use common
error handling for xfs_bwrite().
__xfs_buf_delwri_submit() is a similar - it's only ever called
on writes - all sync or async - and again there's no reason to
handle them any differently at all.
Clean up the nasty error handling and remove xfs_bioerror().
