bonding: Convert balance-rr transmit to new locking

Change locking in balance-rr transmit processing to use a free
running counter to determine which slave to transmit on.  Instead, a
free-running counter is maintained, and modulo arithmetic used to select
a slave for transmit.

This removes lock operations from the TX path, and eliminates
a deadlock introduced by the conversion to work queues.
