Fix a regression where hv_root_crash_init() fails a hypercall because
the hypercall page is not fully setup. The regression is caused by
following commit:

commit c8ed0812646e ("x86/hyperv: Use direct call to hypercall-page")


Is that the right commit? The named commit was merged in v6.18-rc1 and
hv_root_crash_init() was only merged in v6.19-rc1...

Ah, you are right. I guess that commit was not in our internal
hyper-next mirror, so testing did not reveal the issue and I did not
notice it. Because of few missing things, we've to use internal mirror
to test. Anyways, will fix the commit and resend.
