[PATCH 21.11] eal: cleanup alarm and hotplug before memory detach

[Fengnan Chang <changfengnan@bytedance.com>]

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.
