net: rtnetlink: fix error handling in rtnl_fill_statsinfo()
The clang static analyzer reports this issue
rtnetlink.c:5481:2: warning: Undefined or garbage
value returned to caller
return err;
^~~~~~~~~~
There is a function level err variable, in the
list_for_each_entry_rcu block there is a shadow
err. Remove the shadow.
In the same block, the call to nla_nest_start_noflag()
can fail without setting an err. Set the err
to -EMSGSIZE.
Fixes: 216e690631f5 ("net: rtnetlink: rtnl_fill_statsinfo(): Permit non-EMSGSIZE error returns")
