hugetlb: abort a hugepage pool resize if a signal is pending
If a user asks for a hugepage pool resize but specified a large number, the machine can begin trashing. In response, they might hit ctrl-c but signals are ignored and the pool resize continues until it fails an allocation. This can take a considerable amount of time so this patch aborts a pool resize if a signal is pending. Suggested by Dave Hansen.
