[PATCH v3 5/6] common/rc: introduce _check_f2fs_filesystem()

[Chao Yu <chao@kernel.org>]

_check_generic_filesystem() will fail the test once it detects
corruption, let's introduce _check_f2fs_filesystem() to just check
filesystem w/ --dry-run option, and return the error number, then
let caller to decide whether the corruption is as expected or not.
