b43: fix shared IRQ race condition

Fix an IRQ race condition in b43. If we call b43_stop_wireless_core(), it
will set the status of the device to INITIALIZED and the IRQ handler won't
care any longer about IRQs, thus the kernel will disable the IRQ if it's
shared (unless we boot it with the 'irqpoll' option). So we must disable
IRQs before changing the device status.
