ml2: remove superfluous %s in LOG.debug() format
ml2: remove superfluous %s in LOG.debug() format

ml2.db.get_dynamic_segment() includes this line:

   LOG.debug("No dynamic segment %s found for "
	     "Network:%(network_id)s, "
	     "Physical network:%(physnet)s, "
	     "segmentation_id:%(segmentation_id)s",
	     {'network_id': network_id,
	      'physnet': physical_network,
	      'segmentation_id': segmentation_id})

Note the superfluous %s in the format string.  At run-time, %s prints
the args hash again and doesn't cause an error, but this is clearly
unintended.

Since there doesn't seem to be any value that was meant to be used
instead, this change simply removes the %s.
