net/core: Remove unused assignment operations and variable
Although if_info_size is assigned, it has not been used. And the variable
should also be deleted.
The clang_analyzer complains as follows:
net/core/rtnetlink.c:3806: warning:
Although the value stored to 'if_info_size' is used in the enclosing
expression, the value is never actually read from 'if_info_size'.
