[PATCH] brcmfmac: clear sdiodev->pdata if irq_of_parse_and_map fails

[Henrik Eriksson <henrik.eriksson@axis.com>]

Clear the pdata pointer in sdiodev after freeing the memory.  In my case
not doing so interferes with device initialization as request_irq of
sdiodev->pdata->oob_irq_nr fails, but even if not, leaving a wild
pointer is incorrect.
