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.
