[SCSI] hpsa: use multiple reply queues

Smart Arrays can support multiple reply queues onto which command
completions may be deposited.  It can help performance quite a bit
to arrange for command completions to be processed on the same CPU
from which they were submitted to increase the likelihood of cache
hits.
