[PATCH] common/rc: f2fs do not support metadata journaling

[Sun Ke <sunke32@huawei.com>]

In generic/50, touch 100 files, go down the fs immediately, Then umount
and set the disk readi-only. Try to mount it again without \-o
norecovery\, it should fail, because it can not recovery on a read-only
device. But f2fs mount successfully and the test fail.

f2fs seems do not support metadata journaling.

I am not very sure if f2fs do not support metadata journaling.
