dns: handle early eof in tcp fallback
A zero returned from recvmsg is currently treated as if some data were
received, so if a DNS server closes its TCP socket before sending the
full answer, __res_msend_rc will spin until the timeout elapses because
POLLIN event will be reported on each poll. Fix this by treating an
early EOF as an error.
