USB: make actual_length in struct urb field u32
actual_length should also be a u32 and not a signed value. This patch
changes this field to be 'u32' to prevent any potential negative
conversion and comparison errors.
This triggered a few compiler warning messages when these fields were
being used with the min macro, so they have also been fixed up in this
patch.
