[hermon] Adjust Ethernet work queue size 

Hermon Ethernet work queues have more RX than TX entries, unlike most
other drivers.  This is possibly the source of some stochastic
deadlocks previously experienced with this driver.

Update the sizes to be in line with other drivers, and make them
slightly larger for better performance.  These new queue sizes have
been found to work well with ConnectX-3 hardware.
