staging: wfx: wfx_init_common() returns NULL on error

Browse source 
Smatch complains:

    bus_spi.c:228 wfx_spi_probe() warn: 'bus->core' could be an error pointer
    bus_sdio.c:221 wfx_sdio_probe() warn: 'bus->core' could be an error pointer

bus->core contains the result of wfx_init_common(). With this patch,
wfx_init_common() returns a valid pointer or NULL.
