net: wireless: bcmdhd: Ensure OOB interrupt is registered
Ensure OOB interrupt is always registered when bus is active.
Fixes this bug:
If there was an SDIO error during the initial firmware download,
the OOB interrupt will not get registered. Then, on subsequent
device resets, the code for registering OOB interrupt did not
get called again - causing a persistent wifi failure.
Bug 1327983
