scsi: lpfc: Fix FLOGI ACC with wrong SID in PT2PT topology
When a FLOGI is received before we have issued our FLOGI, the ACC response
to the received FLOGI is issued with SID 2 instead of the expected fabric
controller SID. Certain target vendors ignore the malformed ACC with SID 2
and wait for a properly filled ACC with a fabric controller SID.
The lpfc_sli_prep_wqe() routine depends on the FC_PT2PT flag to fill in the
fabric controller SID when in PT2PT mode, but due to a previous commit the
flag was getting cleared. Fix by adding a check for the defer_flogi_acc
flag to know whether or not to clear the FC_PT2PT flag on link up.
