On hardware reintialization reference count of
already existing timers would be increased again.
This leads to problems on module unloading.

Hi John,
This patch fixes driver unload issue after driver restart due
to fatal hardware problem. Because for 3.8 brcmsmac has been
reported to restart (looking into that) this fix may be helpful
to at least get the driver removed.
