Most calls to xfs_finish_inode_setup are for error cases that
just drop the inode instantly and don't need it.  The other
cases are:

 - xfs_generic_create, xfs_vn_symlink and xfs_setup_existing_inode,
   which are handled in this patch
 - xfs_qm_qino_alloc, which is for the quota inode that doesn't have
   inode operations
 - xfs_rename_alloc_whiteout which probably needs it.  This seems
   to be recent and has no apparent test coverage, so I'm not sure
   how to verify it, though.
