Skip numa usage update for update_available_resource task

Current thoughts that update_available_resource could be the source
of troubles for CPU pin/unpin. New CPU pinning for migrated instance
could be incompatible with the old compute node. This causes fail
in periodic tasks like update_available_resource as it's check
resources for the old compute node. Effectively this means
that instance numa topology is updated but instance host is not.

This patch skips numa usage update while instance in a migration
state, for other states it's same as it was.
