In (recent versions of?) macOS, calls to hv_vcpu_set_sys_reg were failing if
they were issued outside of the specific thread that owns the vCPU.

This caused a crash when attaching a debugger through the GDB stub.

This GDB stub has worked before, so it is unclear if Apple changed the
behavior of the function in a release of macOS.

Mads Ynddal (2):
  hvf: avoid repeatedly setting trap debug for each cpu
  hvf: only update sysreg from owning thread
