f2fs: fix to restrict mount condition on readonly block device

When we mount an unclean f2fs image in a readonly block device, let's
make mount() succeed only when there is no recoverable data in that
image, otherwise after mount(), file fsyned won't be recovered as user
expected.

Fixes: 938a184265d7 ("f2fs: give a warning only for readonly partition")
