daemon-server: fix error message on daemon shutdown

Browse Source 
If a daemon (like lvmetad that is using common daemon-server code)
received a kill signal that was supposed to shut the daemon down,
a spurious message was issued: "Failed to handle a client connection".

This happened if the kill signal came just in the middle of waiting
for a client request in "select" - the request that was supposed to
be handled was blank at that moment of course.
