net/esp4: Fix invalid esph pointer crash
Both esp_output and esp_xmit take a pointer to the ESP header
and place it in esp_info struct prior to calling esp_output_head.
Inside esp_output_head, the call to esp_output_udp_encap
makes sure to update the pointer if it gets invalid.
However, if esp_output_head itself calls skb_cow_data, the
pointer is not updated and stays invalid, causing a crash
after esp_output_head returns.
Update the pointer if it becomes invalid in esp_output_head
Fixes: fca11ebde3f0 ("esp4: Reorganize esp_output")
