The softclock_call_cc() is executing with the callout already removed
from the callwheel. Calculate the cc->cc_next before removing the
callout, otherwise the code followed the invalid tailq links.  After
this, make softclock_call_cc() return void, since it always return
cc->cc_next, which is immediately available to the softclock()
anyway. This also allows to eliminate a label under #ifdef SMP.

Remove the assignment of cc->cc_next from callout_cc_del(), since the
function is called with the callout already removed from callwheel.

If cancelling the migration, also clear the CALLOUT_DFRMIGRATION flag.

Postpone the free of the timeout(9) allocated callouts after the
migration checks are done.

Add some more strict asserts about the state of the callout in
callout_call_cc().
