HID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer
quickspi_hid_raw_request() receives the caller's buffer length in len, but
quickspi_get_report() never sees it and copies the whole device-supplied
response into buf regardless:
memcpy(buf, qsdev->report_buf, qsdev->report_len);
qsdev->report_len comes from the input report the touch controller returns,
while buf is sized to whatever the caller asked hidraw for through
HIDIOCGFEATURE or HIDIOCGINPUT. A response larger than that overflows buf
with device-controlled content.
The intel-quicki2c sibling already passes the caller length down to
quicki2c_get_report() and validates the response against it before the
copy. Do the same here.
