Fix deadlock caused by race between xfs_iunpin marking an inode
dirty, and the same inode being reallocated and reused by create.
The unlock_new_inode and mark_inode_dirty manage to corrupt the
i_state flags and end up leaving I_LOCK|I_NEW set.

Modid:  2.4.x-xfs:slinx:151120a
linux/fs/xfs/xfs_inode.c - 1.377
        - do not call mark_inode_dirty in xfs_iunpin when I_NEW is set,
          it is in the process of going into a transaction which will
          also mark it dirty.
