[PATCH v3 2/2] fastboot: bail if update handler couldn't be found for bbu-partition

[Ahmad Fatoum]

Fastboot would fall back to a raw copy even for bbu- partitions if
no barebox_update handler was found. Prevent this by bailing out
with an error code.

v2 -> v3:
  - bail out instead of only printing message and falling back
    to raw copy (Sascha)
v1 -> v2:
  - print message in case barebox_update handler is not found
