Log:
  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.
