scsi: lpfc: Honor module parameter lpfc_use_adisc
commit 0fd103ccfe6a06e40e2d9d8c91d96332cc9e1239 upstream.
The initial lpfc_desc_set_adisc implementation in commit
dea3101e0a5c ("lpfc: add Emulex FC driver version 8.0.28") enabled ADISC if
cfg_use_adisc && RSCN_MODE && FCP_2_DEVICE
In commit 92d7f7b0cde3 ("[SCSI] lpfc: NPIV: add NPIV support on top of
SLI-3") this changed to
(cfg_use_adisc && RSC_MODE) || FCP_2_DEVICE
and later in commit ffc954936b13 ("[SCSI] lpfc 8.3.13: FC Discovery Fixes
and enhancements.") to
(cfg_use_adisc && RSC_MODE) || (FCP_2_DEVICE && FCP_TARGET)
A customer reports that after a devloss, an ADISC failure is logged. It
turns out the ADISC flag is set even the user explicitly set lpfc_use_adisc
= 0.
