x86/xen: use vmap() to map grant table pages in PVH guests
commit 7d951f3ccb0308c95bf76d5eef9886dea35a7013 upstream.
Commit b7dd0e350e0b (x86/xen: safely map and unmap grant frames when
in atomic context) causes PVH guests to crash in
arch_gnttab_map_shared() when they attempted to map the pages for the
grant table.
This use of a PV-specific function during the PVH grant table setup is
non-obvious and not needed. The standard vmap() function does the
right thing.
