net: mana: hardening: Reject zero max_num_queues from MANA_QUERY_VPORT_CONFIG
As a part of MANA hardening for CVM, validate that max_num_sq and
max_num_rq returned by MANA_QUERY_VPORT_CONFIG are not zero. These
values flow into apc->num_queues, which is used as an allocation count
and loop bound. A zero value would result in zero-size allocations and
incorrect driver behavior.
Return -EPROTO if either value is zero.
