[SCSI] lpfc 8.3.23: Fixes related to new hardware

Fixes related to new hardware

- Restrict driver to look at BAR2 or BAR4 only for if_type 0.
- Allow SLI4 with FCOE_MODE not set for new SLI4 FC adapters.
- Add Temporary RPI field to the ELS request WQE.
- Do not override CT field in issue_els_flogi for SLI4 IF type 2
- For RQ_CREATE_V2 mbx cmd: fill in the rqe_size and page_size for RQ_CREATE.
