wmt(4): Fix regression introduced in r337289

Browse Source 
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.
