HID: ft260: improve error handling of ft260_hid_feature_report_get()
The ft260_hid_feature_report_get() checks if the return size matches the
requested size. But the function can also fail with at least -ENOMEM. Add the
< 0 checks.
In ft260_hid_feature_report_get(), do not do the memcpy to the caller's buffer
if there is an error.
