[SCSI] bfa: Fix Command Queue (CPE) full condition check and ack CPE interrupt.
Fixed the issue of not acknowledging the command queue
full-to-non-full interrupt. Implemented separate acknowledging
functions for different ASIC and interrupt mode.
Fixed the case of missing CPE interrupt by always processing the
pending requests in the completion path.
