Log: wmt(4): Fix regression introduced in r337289 r337289 has a side effect of reducing usb frame 0 buffer size down to touch report size. That broke some devices e.g. "Raydium Touch System" which are capable of generating non-touch frames of bigger length. Fix it with enlarging frame 0 buffer up to internal wmt(4) buffer size.
