commit 52daa6a8483e4fbd6757c9d1b791e23931791608

    xen/gnttab: fix gnttab_acquire_resource()
    
    Commit 9dc46386d89d ("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.

warning")
