xfs: remove xfs_iput_new
We never get an i_mode of 0 or a locked VFS inode until we pass in the XFS_IGET_CREATE flag to xfs_iget, which makes xfs_iput_new equivalent to xfs_iput for the only caller. In addition to that xfs_nfs_get_inode does not even need to lock the inode given that the generation never changes for a life inode, so just pass a 0 lock_flags to xfs_iget and release the inode using IRELE in the error path.
