net: remove sock_i_uid()

Difference between sock_i_uid() and sk_uid() is that
after sock_orphan(), sock_i_uid() returns GLOBAL_ROOT_UID
while sk_uid() returns the last cached sk->sk_uid value.

None of sock_i_uid() callers care about this.

Use sk_uid() which is much faster and inlined.

Note that diag/dump users are calling sock_i_ino() and
can not see the full benefit yet.
