preprocess_request skips any node whose nodehm entry has neither cons nor
serialport. That is the right default while scanning the whole table, but it
also drops nodes the administrator named on the command line, leaving the
dispatched node list empty. makeconfluentcfg then falls back to reading every
node, so naming one console-less node quietly configures the whole cluster
instead of the node that was asked for.
A named node with no nodehm row at all is worse: both the selection here and
the second lookup in makeconfluentcfg produce an undefined entry, which reaches
confluent as an empty node name.
Apply the skip only to the full table scan, and carry the node name through
both lookups when the nodehm row is missing. Nodes without a console method are
already handled downstream, where makeconfluentcfg keeps explicitly named
entries and donodeent falls back to hardware management credentials.

makeconfluentcfg -d erroneously would exit after only considering
the first possible node. Allow it to iterate over all the
confluent nodes seeking a match.
