Guenter Roeck 59d104b54b hwmon: (nzxt-smart2) Stop device IO before calling hid_hw_stop
Calling hid_hw_stop() does not stop the device IO.
This results in a race condition between hid_input_report() and the point
immediately following the execution of hid_device_io_start() within
the driver probe function. If the probe operation fails after "io start"
has been initiated, this race condition will result in a UAF vulnerability.

Fix the problem by calling hid_device_io_stop() before calling
hid_hw_stop().
