USB: Pack the usb_request_data struct.

Browse Source 
We really should not be writing raw structs out to devices
for endianness' sake, but that's currently what *all* the
USB bus drivers do with this struct. So, add the _PACKED flag
to ensure it's always precisely 8 bytes.

Additionally, remove memory_chunk, as nothing uses it anymore.
