xen/arm: Print correct domid in allocate_memory_11

[PATCH] xen/arm: Print correct domid in allocate_memory_11

Posted by Michal Orzel 3 weeks, 6 days ago

allocate_memory_11() can be called for dom0 and direct-mapped hwdom
domU. In the latter scenario, a log message would still mention dom0
instead of the correct domid.

Fixes: 52cb53f1816a ("xen/arm: dom0less hwdom construction")
