    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.
