[SCSI] lpfc 8.3.4: Various SLI4 fixes 



Various SLI4 fixes

- Fix switch name not used in the FCF record for FCoE HBAs
- Enabled HBA UE error polling error-condition action code
- Rewrite lpfc_sli4_scmd_to_wqidx_distr() to handle counter rollover cleanly
- Modify resume_rpi mailbox data structure to match current SLI4 spec
- Do not issue mailbox command in MBX_POLL mode when LPFC_HBA_ERROR is set
- Wait for HBA POST completion before checking Online and UE registers
- Fix accumulated total length not being filled in on unsolicited IOCBs
- Use PCI config space register to determine SLI rev of HBA
- Turn on starting ELS tmo function timer during device initialization
