xfrm: Remove duplicate assignment
The statement in the switch is repeated with the statement at the beginning of the while loop, so this statement is meaningless. The clang_analyzer complains as follows: net/xfrm/xfrm_policy.c:3392:2 warning: Value stored to 'exthdr' is never read Reported-by: Zeal Robot <zealci@zte.com.cn> Signed-off-by: luo penghao <luo.penghao@zte.com.cn> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
