Log the connection name when timing out

[fosterseth]

We should name which connection timed out here. It isn't easy from the logs to determine which connection was dropped.

receptor/pkg/netceptor/netceptor.go

Line 780 in 8d5dcca

timedOut[i]()

Easiest way to hit this error message is to drop traffic, e.g. if I have 2 local nodes, connected on tcp port 2222

sudo ip6tables -D INPUT -p tcp -s localhost -d localhost --dport 2222 -j DROP

same with this line

receptor/pkg/netceptor/netceptor.go

Line 909 in 8d5dcca

s.Logger.Debug("connInfo cancelled during flood write")

we should list the connection name
