scsi: lpfc: Allow DEVICE_RECOVERY mode after RSCN receipt if in PRLI_ISSUE state
Certain vendor specific targets initially register with the fabric as an
initiator function first and then re-register as a target function
afterwards.
The timing of the target function re-registration can cause a race
condition such that the driver is stuck assuming the remote port as an
initiator function and never discovers the target's hosted LUNs.
Expand the nlp_state qualifier to also include NLP_STE_PRLI_ISSUE because
the state means that PRLI was issued but we have not quite reached
MAPPED_NODE state yet. If we received an RSCN in the PRLI_ISSUE state,
then we should restart discovery again by going into DEVICE_RECOVERY.
