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.

Return FAILED from eh_ routines if command(s) is(are) not completed

There were scenarios where we may have returned from the error
handlers prior to all affected commands being flushed to the midlayer.
Add changes to ensure this doesn't happen.

Replace lpfc_sli_issue_iocb_wait_high_priority with lpfc_sli_issue_iocb_wait.

Simplify code paths, as there really wasn't a "priority"

There were scenarios where the error handlers could reuse an iotag
value of an active io.  Remove all possibility of this by
pre-assigning iotag resources to command resources.
