ums: always initialize mmc before ums_disk_init()

Browse source 
In cases when MMC hadn't been initialized before, ie. by the user or other
subsystem, it was still uninitialized while UMS media capacity check,
leading to broken ums command.

UMS has to initialize resources it uses.

Tested on Samsung Goni.
