Johan Hovold ba3b9429de mmc: vub300: fix NULL-deref on disconnect 
commit dff34ef879 upstream.

Make sure to deregister the controller before dropping the reference to
the driver data on disconnect to avoid NULL-pointer dereferences or
use-after-free.

Fixes: 88095e7b47 ("mmc: Add new VUB300 USB-to-SD/SDIO/MMC driver")
