Subject: [PATCH 2/4] xfs: unlock inode when xfs_ioctl_setattr_get_trans
 can't get transaction

From: Darrick J. Wong <darrick.wong@...cle.com>

We passed an inode into xfs_ioctl_setattr_get_trans with join_flags
indicating which locks are held on that inode.  If we can't allocate a
transaction then we need to unlock the inode before we bail out.
