wayland-server: Return 0 from read_events() in case of EAGAIN
Getting no data from the socket is not an error condition. This may
happen in case of calling prepare_read() and then read_events() with
no other pending readers and no data in the socket. In general,
read_events() may not queue up events in the given event queue. From
a given threads point of view it doesn't matter whether events were
read and put in a different event queue or no events were read at all.
