[PATCH] 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.
