scsi: lpfc: Refactor lpfc_nvmet_prep_abort_wqe() into lpfc_sli_prep_abort_xri()

BugLink: https://bugs.launchpad.net/bugs/1988711

lpfc_nvmet_prep_abort_wqe() has a lot of common code with
lpfc_sli_prep_abort_xri().

Delete lpfc_nvmet_prep_abort_wqe() as the wqe can be filled out using the
generic lpfc_sli_prep_abort_xri routine(). Add the wqec option to
lpfc_sli_prep_abort_xri() for lpfc_nvmet_prep_abort_wqe().

scsi: lpfc: Revert RSCN_MEMENTO workaround for misbehaved configuration

BugLink: https://bugs.launchpad.net/bugs/1988711

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.

scsi: lpfc: Fix lost NVMe paths during LIF bounce stress test

BugLink: https://bugs.launchpad.net/bugs/1988711

During a target link bounce test, the driver sees a mismatch between the
NPortId and the WWPN on the node structures (ndlps) involved. When this
occurs, the driver "swaps" the ndlp and new_ndlp node parameters to restore
WWPN/DID uniqueness in the fc_nodes list per vport. However, the driver
neglected to swap the nlp_fc4_type in the ndlp passed to
lpfc_plogi_confirm_nport causing a failure to recover the NVMe PLOGI/PRLI
and ultimately the NVMe paths.

Correct confirm_nport to preserve the fc4 types from the new-ndlp when the
data is moved over ot the ndlp structure.

There is no corresponding free routine if lpfc_sli4_issue_wqe fails to
