vfs: fix freeze protection in mnt_want_write_file() for overlayfs
[ Upstream commit a6795a585929d94ca3e931bc8518f8deb8bbe627 ]
The underlying real file used by overlayfs still contains the overlay path.
This results in mnt_want_write_file() calls by the filesystem getting
freeze protection on the wrong inode (the overlayfs one instead of the real
one).
Fix by using file_inode(file)->i_sb instead of file->f_path.mnt->mnt_sb.
