HTTP/2: avoid sending output queue if there's nothing to send. Particularly this fixes alerts on OS X and NetBSD systems when HTTP/2 is configured over plain TCP sockets. On these systems calling writev() with no data leads to EINVAL errors being logged as "writev() failed (22: Invalid argument) while processing HTTP/2 connection".
