mpm_event: don't reset connections after lingering close timeout

While httpd is supposed to do lingering close for incoming data, it has no
control anyway over outgoing/pending data once they are handled by the
system.

So don't reset the connection after lingering close times out, otherwise the
system won't do its own lingering close to flush un-acked data.

The connection reset was introduced by r1802875 and backported to 2.4.28.
