scpi-pps: Fix dev_clear() implementation

Devices for the scpi-pps driver do have additional data attached to it that
needs to be freed when the device is freed. While the driver gets it right
for the cleanup() callback it does not for the dev_clear() callback. This
will cause memory leaks when sr_dev_clear() is called for this driver.

To fix this let the dev_clear() free the additional data.
