Juergen Gross b956076239 xen/gnttab: fix gnttab_acquire_resource()

Commit 9dc46386d8 ("gnttab: work around "may be used uninitialized"
warning") was wrong, as vaddrs can legitimately be NULL in case
XENMEM_resource_grant_table_id_status was specified for a grant table
v1. This would result in crashes in debug builds due to
ASSERT_UNREACHABLE() triggering.

Check vaddrs only to be NULL in the rc == 0 case.

Expand the tests in tools/tests/resource to tickle this path, and verify that
using XENMEM_resource_grant_table_id_status on a v1 grant table fails.
