um: ubd: Initialize ubd's disk pointer in ubd_add
[ Upstream commit df700802abcac3c7c4a4ced099aa42b9a144eea8 ]
Currently, the initialization of the disk pointer in the ubd structure
is missing. It should be initialized with the allocated gendisk pointer
in ubd_add().
Fixes: 32621ad7a7ea ("ubd: remove the ubd_gendisk array")
