Fix polling of socket with negative timeout (when poll() interrupted by EINTR)

Browse Source 
In case of EINTR the timeout will be adjusted, but this should not be
done in case of negative timeout since it means infinite timeout, and
in that adjustment block negative timeout will be reset to 0, which will
make poll() return (since zero timeout means return immediatelly even if
no fd is ready).

This should also fix 02127_connection_drain flap on CI [1].
