hyperv: Fix boot-up after malloc() returns memory of NX by default now
FreeBSD VM can't boot up on Hyper-V after the recent malloc change in r335068: Make UMA and malloc(9) return non-executable memory in most cases. The hypercall page here must be executable. Fix the boot-up issue by adding M_EXEC. PR: 229167 Sponsored by: Microsoft
