hwmon: (w83791d) remove fan/pwm 4-5 sysfs group on remove

In the Linux kernel, the following vulnerability has been resolved:

hwmon: (w83791d) remove fan/pwm 4-5 sysfs group on remove

When the fan/pwm 4-5 pins are not used as GPIO, w83791d_probe()
creates the w83791d_group_fanpwm45 sysfs group on the I2C client
device.

The probe error path removes this group when a later initialization
step fails, but the normal remove path only removes w83791d_group.
As a result, the optional fan/pwm 4-5 sysfs files can remain after the
driver is unbound.

The callbacks associated with these files access the driver data,
which is devm allocated and released after driver unbind. Leaving the
sysfs files behind can therefore result in accesses to stale driver
data.

Remove w83791d_group_fanpwm45 during normal teardown as well.

This issue was found by manual code inspection.
