[PATCH] xfs: fix xfs_ifree() error handling to not leak perag ref

[Brian Foster <bfoster@redhat.com>]

For some reason commit 9a5280b312e2e ("xfs: reorder iunlink remove
operation in xfs_ifree") replaced a jump to the exit path in the
event of an xfs_difree() error with a direct return, which skips
releasing the perag reference acquired at the top of the function.
Restore the original code to drop the reference on error.
