fs: Fix S_NOSEC handling
commit 2426f3910069ed47c0cc58559a6d088af7920201 upstream.
file_remove_suid() could mistakenly set S_NOSEC inode bit when root was
modifying the file. As a result following writes to the file by ordinary
user would avoid clearing suid or sgid bits.
Fix the bug by checking actual mode bits before setting S_NOSEC.
