vfs: Use IOP_XATTR flag for bad-inode handling
With this change, all the xattr handler based operations will produce an -EIO result for bad inodes, and we no longer only depend on inode->i_op to be set to bad_inode_ops. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
