    Since there's no easy way to gracefully deal
    with interruptions, fix the driver to not use
    interruptible waits.

    This at least fixes the error
    iwlagn 0000:02:00.0: Error: Response NULL in  'REPLY_SCAN_ABORT_CMD'

    I have seen in P2P testing, but it is likely
    that there are other errors caused by this.
