Run audio interrupts without grabbing the kernel lock. While IPL_SERIAL is
higher than IPL_AUDIO on sparc64, and interrupt handlers running at IPL_SERIAL
still grab the kernel lock, this isn't a problem as machines with audioce(4)
are guaranteed not to have zs(4) (the only driver that uses IPL_SERIAL).
