hwmon: (w83793) remove vrm sysfs file on probe failure

w83793_probe() creates the vrm sysfs file after creating the VID files
when VID support is present.

The normal remove path deletes vrm, but the probe error path only
removes the sensor, SDA, VID, fan, PWM and temperature files.  A later
probe failure can therefore leave vrm behind after the driver data has
been freed.

Remove vrm in the probe error path next to the VID files, matching the
normal remove path.
