rtnetlink_server: Ignore errors on ignored interfaces

An example is MCTP device addresses that cannot be parsed by
phosphor-networkd. We don't need to parse them if they are ignored, so
we can just ignored the errors.

Tested: Verified that MCTP devices no longer cause error messages to
print to the journal.
