HID: i2c-hid: fix GET/SET_REPORT for unnumbered reports
Internally kernel prepends all report buffers, for both numbered and
unnumbered reports, with report ID, therefore to properly handle unnumbered
reports we should prepend it ourselves.
For the same reason we should skip the first byte of the buffer when
calling i2c_hid_set_or_send_report() which then will take care of properly
formatting the transfer buffer based on its separate report ID argument
along with report payload.
