dm: blk: Use uclass_find_first/next_device() in blk_first/next_device()

This patch changes the calls to uclass_first/next_device() in blk_first/
next_device() to use uclass_find_first/next_device() instead. These functions
don't prepare the devices, which is correct in this case.

With this patch applied, the "usb storage" command now works again as
expected:

=> usb storage
  Device 0: Vendor: SanDisk Rev: 1.00 Prod: Ultra
  Type: Removable Hard Disk
  Capacity: 58656.0 MB = 57.2 GB (120127488 x 512)

Without this patch, it used to generate this buggy output:

=> usb storage
Card did not respond to voltage select!
mmc_init: -95, time 26
No storage devices, perhaps not 'usb start'ed..?
