The bonding driver's bond_select_queue function simply returns
skb->queue_mapping.  However queue_mapping could be == 16
for queue #16.  This causes the following message to be flooded
to syslog:

kernel: bondx selects TX queue 16, but real number of TX queues is 16

ndo_select_queue wants a zero-based number, so bonding driver needs
to subtract one to return the proper queue number.  Also fix grammar in
a comment while in the vicinity.
