f2fs: fix to clean previous mount option when remount_fs In manual of mount, we descript remount as below: "mount -o remount,rw /dev/foo /dir After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command." Previously f2fs do not clear up old mount options when remount_fs, so we have no chance of disabling previous option (e.g. flush_merge). Fix it.
