USB: gadget: f_mtp: Support for file transfer length greater than 4 gigabytes
For backward compatibility with PTP, MTP is limited to a 32-bit file size.
When transferring files greater than 4 gig, MTP uses 0xFFFFFFFF as the file size
and the receiver reads until it receives a short packet.
Expanded size of mtp_file_range.length to 64 bits and added support for
writing zero length packets.
