[PATCH] remove_suid() should return error code

From: Nikita Danilov <Nikita@Namesys.COM>

remove_suid() ignores return value of notify_change()->i_op->setattr().
This mean, that even if file system fails to clear suid bit,
generic_file_aio_write_nolock() proceeds with write, which is unsafe.

Actually, even ext2's ->setattr() can fail, when trying to update ACL, for
example.

Attached patch modifies remove_suid() to return result of ->setattr(), and
updates in-tree callers.
