[U-Boot] [PATCH] dm: blk: Fix get_desc to return block device descriptor

[Michal Simek]

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.

I have tested it with blk scsi which I am reworking after first RFC.
With this patch I can run scsi part, scsi info, scsi read (I didn't test
write not to break my HDD).
