ath5k: use spin_lock_irqsave for beacon lock
ath5k_reset can be called from process context, which in turn can
call ath5k_beacon_config which takes the sc->block spinlock. Since
it can also be taken in hard irq context, use spin_lock_irqsave
everywhere. This fixes a potential deadlock in adhoc mode.
