fsck.f2fs: relocate chksum verification step during f2fs_do_mount()

Keep sanity_check_raw_super flow in fsck.f2fs being consistent w/
sanity_check_raw_super() in f2fs kernel module, otherwise, it outputs
different error information when mounting/fscking the same image which
contains corrupted superblock.
