staging: rtl8712: fix race condition
In probe function, request_firmware_nowait() is called to load firmware
asynchronously. At completion of firmware loading, register_netdev() is
called. However, a mutex needed by netdev is initialized after the call
to request_firmware_nowait(). Consequently, it can happen that
register_netdev() is called before the driver is ready.
Move the mutex initialization into r8712_init_drv_sw(), which is called
before request_firmware_nowait().
