smartmontools: fix panic on INVARIANTS enabled kernel after r308351 in base

    After r308351 commit the INVARIANTS enabled kernel gets too "eager" when
    checking the cam ccb flags. But the real problem was not the previous, but
    the smartmontools does not zeroed out the ccb on stack, and pass this
    dirty ccb to kernel, which is catched by an ASSERT. So fix this by filling
    up with 0 this ccb. This commit is similar, what's happen in r307684
    in camcontrol. So this is the same followup patch in smartmontools.
