net: ena: fix PHC cleanup on probe failure

ena_probe() initializes the PHC as part of ena_device_init(), but the
probe failure path does not destroy it before freeing the PHC private
data.

The normal removal path calls ena_phc_destroy() through
ena_destroy_device() before ena_phc_free(). However, if probe fails
after ena_device_init() succeeds, the error path reaches ena_phc_free()
without unregistering the PTP clock or destroying the device PHC
resources.

Call ena_phc_destroy() in the probe error path before freeing the PHC
private data.

This issue was found by manual code inspection.
