[SCSI] qla2xxx: Update to AER support, do early abort commands.

Currently the IOs are returned back in slot reset, this
could be late and can cause error handler to invoke.
If error handler invokes, eh_abort fails and escalate to
device/bus/host resets causing issues.
The commands need to be returned back to upper layer in
io_error_detected.
