dm: blk: Fix get_desc to return block device descriptor

Browse Source 
Current get_desc() implementation is not able to succesfully
finish and return pointer to block device descriptor.

Also function always return non zero value even device is found.

The patch fills block device descriptor and return 0 if device is found.
