scsi: qla2xxx: don't break the bsg-lib abstractions

Browse Source 
Always use bsg_job->reply instead of scsi_req(bsg_job->req)->sense), as
they always point to the same memory.

Never set scsi_req(bsg_job->req)->result and we'll set that value
through bsg_job_done.

[mkp: applied by hand, fixed whitespace]
