f2fs: handle remount options correctly
The current f2fs code errors if the xattr or acl options are passed when remounting. This is important in a typical scenario where f2fs is mounted as a "ro" root file-system by the boot loader and then the init process wants to remount it "rw" with the "remount,rw" option.
