wilc1000: fix double free error in probe()
Smatch complains that there is a double free in probe:
drivers/net/wireless/microchip/wilc1000/spi.c:186 wilc_bus_probe() error: double free of 'spi_priv'
drivers/net/wireless/microchip/wilc1000/sdio.c:163 wilc_sdio_probe() error: double free of 'sdio_priv'
The problem is that wilc_netdev_cleanup() function frees "wilc->bus_data".
That's confusing and a layering violation. Leave the frees in probe(),
delete the free in wilc_netdev_cleanup(), and add some new frees to the
remove() functions.
