compat-drivers: fix compilation on 2.6.30

Commit cfe9f9 did indeed fix the new changes on the TI
driver for newer kernels but failed to address the removal
of the wl12xx_hardirq handle no longer required for older
kernels. Fix this.

    compat-drivers: fix collateral-evolutions/network/09-threaded-irq.patch

    Manual edits required due to some context changes. The change
    in question that caused this is

        wlcore: move handling from hardirq to the irq thread function

        Spin locks and completions are expensive in hard IRQ context and cause
        problems with RT kernels.  In RT kernels, both spin locks and
        completions can schedule(), so we can't use them in hard irq context.

        Move handling code into the irq thread function to avoid that.
