HID: holtek: fix mouse probing

stable inclusion
from stable-v5.10.89
commit 3110bc5862d213035c685ed607795e6abdb34d78
bugzilla: 186140 https://gitee.com/openeuler/kernel/issues/I4S8HA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=3110bc5862d213035c685ed607795e6abdb34d78

--------------------------------

commit 93a2207c upstream.

An overlook from the previous commit: we don't even parse or start the
device, meaning that the device is not presented to user space.

Fixes: 93020953 ("HID: check for valid USB device for many HID drivers")
