scsi: qedf: Modify flush routine to handle all I/Os and TMF
The purpose of flush routine is to cleanup I/Os to the firmware and
complete them to scsi middle layer. This routine is invoked before
connection is uploaded because of rport going away.
- Don't process any I/Os, aborts, TMFs coming when flush in progress.
- Add flags to handle cleanup and release of I/Os because flush can
prematurely complete I/Os.
- Original command can get completed to driver when cleanup for same is
posted to firmware, handle this condition.
- Modify flush to handle I/Os in all the states like abort, TMF, RRQ and
timeouts.
