tap: Check return value of accept4() before calling getsockopt()
Reported by Coverity (CWE-119):
Negative value used as argument to a function expecting a
positive value (for example, size of buffer or allocation)
and harmless, because getsockopt() would return -EBADF if the
socket is -1, so we wouldn't print anything.
Check if accept4() returns a valid socket before calling getsockopt()
on it.
