[SCSI] lpfc 8.3.28: Critical Miscellaneous fixes 

- Make lpfc_sli4_pci_mem_unset interface type aware (CR 124390)
- Convert byte count to word count when calling __iowrite32_copy (CR 122550)
- Checked the ERR1 and ERR2 registers for error attention due to SLI
  Port state affected by forced debug dump. (CR 122986, 122426, 124859)
- Use the lpfc_readl routine instead of the readl for the port status
  register read in lpfc_handle_eratt_s4 (CR 125403)
- Call lpfc_sli4_queue_destroy inside of lpfc_sli4_brdreset before doing
  a pci function reset (CR 125124, 125168, 125572, 125622)
- Zero out the HBQ when it is allocated (CR 125663)
- Alter port reset log messages to indicate error type (CR 125989)
- Added proper NULL pointer checking to all the places that accessing
  the queue memory (CR 125832)
