usb: raw-gadget: do not limit transfer length

Browse source 
commit 37b9dd0d11 upstream.

Drop the check on the maximum transfer length in Raw Gadget for both
control and non-control transfers.

Limiting the transfer length causes a problem with emulating USB devices
whose full configuration descriptor exceeds PAGE_SIZE in length.

Overall, there does not appear to be any reason to enforce any kind of
transfer length limit on the Raw Gadget side for either control or
non-control transfers, so let's just drop the related check.
