b44: fix resume, request_irq after hw reset

On resume, call request_irq() after resetting the hardware rather than
before. It's a shared interrupt so the handler could be called
immediately if another device on the same irq interrupts (and will be
called immediately if CONFIG_DEBUG_SHIRQ=y), but unless the hardware is
reinitialised with b44_init_hw() the read of the interrupt status
register will hang the system.
