xen/grant-table: Refactor gnttab_init

We have this odd scenario of where for PV paths we take a shortcut
but for the HVM paths we first ioremap xen_hvm_resume_frames, then
assign it to gnttab_shared.addr. This is needed because gnttab_map
uses gnttab_shared.addr.

Instead of having:
	if (pv)
		return gnttab_map
	if (hvm)
		...

	gnttab_map

Lets move the HVM part before the gnttab_map and remove the
first call to gnttab_map.
