From: penghao luo <luo.penghao@zte.com.cn>

the variable err is not necessary in such places. It should be revmoved
for the simplicity of the code.

The clang_analyzer complains as follows:

net/xfrm/xfrm_input.c:530: warning:

Although the value stored to 'err' is used in the enclosing expression,
the value is never actually read from 'err'.
