tap: Avoid bogus missingReturn cppcheck warning in tap_l2_max_len()

Cppcheck 2.14.2 on Alpine Linux (musl) says that:

tap.c:111:19: error: Found an exit path from function with non-void return type that has missing return statement [missingReturn]
 switch (c->mode) {
                  ^

This exit path is not reachable because we ASSERT(0) after the switch,
but for some reason cppcheck doesn't see this with musl headers. Hide
the warning with a redundant return statement.
