[PATCH 05/44] lpfc: don't use fc_bsg_job::request and fc_bsg_job::reply directly

From: Johannes Thumshirn
Date: Tue Oct 11 2016 - 07:39:10 EST

Don't use fc_bsg_job::request and fc_bsg_job::reply directly, but use
helper variables bsg_request and bsg_reply. This will be helpfull when
transitioning to bsg-lib.
