usb: dwc2: remove restriction on buffer length

Each USB transfer is split up into chunks that are held in an aligned
buffer. This imposes a limit on the size of each chunk, but no limit on
the total size of transferred data. Fix the logic in chunk_msg() not to
reject large transfers, but simply take the size of the aligned buffer
into account when calculating the chunk size.
