[SCSI] qla2xxx: Code changes for qla data structure refactoring
Following changes have been made:
1. Outstanding commands are based on a request queue, scsi_qla_host
does not maintain it anymore.
2. start_scsi is accessed via isp_ops struct instead of direct
invocation.
3. Interrupt registrations are done using response queue instead of
device id.
