scsi: lpfc: Revert RSCN_MEMENTO workaround for misbehaved configuration
The RSCN_MEMENTO logic was to workaround a target that does not register
both FCP and NVMe FC4 types at the same time. This caused the
configuration to not produce a second RSCN for the NVMe FC4 type
registration in a timely manner. The intention of the RSCN_MEMENTO flag
was to always signal to try NVMe PRLI.
However, there are other FCP-only target arrays in correctly behaved
configurations that reject the NVMe PRLI followed by a LOGO leading to
never rediscovering the target after an issue_lip (as LOGO causes a repeat
of PLOGI/PRLIs).
Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to
fail while it exists only to succeed on a misbehaved config.
