eal: cleanup alarm and hotplug before memory detach

Alarm and multiprocess hotplug still need access hugepage memory,
if alarm event processed after memory detach, it may cause SEGV.
So cleanup alarm and multiprocess hotplug before memory detach.

Fixes: 90b13ab ("alarm: remove direct access to interrupt handle")
Fixes: a0cc7be ("mem: cleanup multiprocess resources")
