[SCSI] lpfc 8.1.12 : Modify ELS abort handling to prevent double completion

Modify ELS abort handling to prevent double completion

Rework portions of ELS abort handling to prevent double completion
 - Rework ELS iotags and correct abort routine
 - Move the (badly wrong) ELS completion logic from the initial ELS
   abort request function to the ELS completion function.
 - Fixup the iocb completion handling to account for the ELS abort
   completions.
