[PATCH v1] x86/hyperv: Move hv crash init after hypercall pg setup

[Mukesh R <mrathor@linux.microsoft.com>]

hv_root_crash_init() is not setting up the hypervisor crash collection
for baremetal cases because when it's called, hypervisor page is not
setup. This got missed due to internal mirror falling behind.

Fix is simple, just move the crash init call after the hypercall
page setup.
