rG7699ec1558b7: hid: Add HQ_NO_READAHEAD quirk and implement it in usbhid(4)

Summary

It disables interrupt emulation on poll-driven buses like USB and
forces aquiring of only one USB frame per read(2) operation.
This avoids an FIDO/U2F issue where IN endpoint data received from
the device right before the file handle is closed, gets lost.
