[NTOS:IO] IoDisconnectInterrupt(): Switch to ExFreePoolWithTag() (#6503)

Follow-up to commit 24a14abf2 (r57412).

HBelusca's comment:
> If this ExFreePoolWithTag() call was left commented, it's probably
> because, back in the day where I introduced it, there was a pool
> corruption that was detected, the source of which was unknown at
> that time. In retrospect, it is most probably the interrupt disconnect
> bug in IoDisconnectInterrupt() that was causing it. Now that this
> bug has been fixed just previously, it should be safe to re-enable
> pool freeing with tag.
