hwmon: (w83793) release probe data through kref

w83793_probe() initializes data->kref to manage the lifetime of the
driver data. The normal remove path drops the driver-owned reference
with kref_put(), while watchdog users take and release additional
references through the same kref.

However, the probe error path still frees data directly with kfree().
This bypasses the kref-managed lifetime and discards the initial
reference without a matching kref_put(), leaving the reference
accounting unbalanced.

Drop the probe-owned reference with kref_put() instead and let
w83793_release_resources() perform the final free, matching the normal
remove path.

This issue was found by manual code inspection.
