[SCSI] lpfc 8.1.7: Misc Fixes 

Misc Fixes:
 - Fix some sparse warnings - casts of address space
 - Fix handling of the adapter registration string. Each invocation
   was byteswapping, so every other adapter init attempt failed.
 - Correct comments and default value for the lpfc_max_luns parameter
