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.
