Hagar Hemdan 8d0d50a8b7 net: esp: cleanup esp_output_tail_tcp() in case of unsupported ESPINTCP 
[ Upstream commit 96f887a612e4cda89efc3f54bc10c1997e3ab0e9 ]

xmit() functions should consume skb or return error codes in error
paths.
When the configuration "CONFIG_INET_ESPINTCP" is not set, the
implementation of the function "esp_output_tail_tcp" violates this rule.
The function frees the skb and returns the error code.
This change removes the kfree_skb from both functions, for both
esp4 and esp6.
WARN_ON is added because esp_output_tail_tcp() should never be called if
CONFIG_INET_ESPINTCP is not set.

This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

Fixes: e27cca96cd ("xfrm: add espintcp (RFC 8229)")
