Replace callout_stop with callout_halt
In order to call callout_destroy for a callout safely, we have to ensure
the function of the callout is not running and pending. To do so, we should
use callout_halt, not callout_stop.
Discussed with martin@ and riastradh@.
Make it clear that we should use not callout_stop but callout_halt
before callout_destroy
Replace callout_stop with callout_halt
In order to call callout_destroy for a callout safely, we have to ensure
the function of the callout is not running and pending. To do so, we should
use callout_halt, not callout_stop.
In this case, we need to pass an interlock to callout_halt to wait for
the callout complete.

Kill sme_callout_mtx and use sme_mtx instead
We can use sme_mtx for the callout as well. Actually we should do so
because sme_events_list and some other data that are touched in the
callout should be protected by sme_mtx, not sme_callout_mtx.

use callout_halt, not callout_stop.
In this case, we need to pass an interlock to callout_halt to wait for
the callout complete. And also we make sure that SME_CALLOUT_INITIALIZED
is unset before calling callout_halt to prevent the callout from calling
callout_schedule. This is the same as what we did in sys/netinet6/mld6.c@1.61.
