USB: make transfer_buffer_lengths in struct urb field u32
Roel Kluin pointed out that transfer_buffer_lengths in struct urb was declared as an 'int'. 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.
