If an ironic node is registered without either of the 'memory_mb' or
'cpus' properties, the following warning messages are seen in the
nova-compute logs:
Warning, memory usage is 0 for <instance> on baremetal node <node>.
Warning, number of cpus is 0 for <instance> on baremetal node <node>.
As of the Stein release [1], the standard compute resources (VCPU,
MEMORY_MB, DISK_GB) are not registered with placement for ironic nodes.
They were not required to be set since the Pike release, but still this
warning is emitted.
This change removes these warning messages.

NOTE(mriedem): The original commit message on this change incorrectly
said that [1] was made in Rocky but it was actually made in Stein.
The important part is that the "memory_mb" and "cpus" properties on
the node could be 0 since Pike and if they are 0, it just means
that the related standard resource class inventory is not reported
to the placement service and thus the warnings are noise.
