MINOR: mux-h1: Remove first useless test on count in h1_process_output()

h1_process_output() function is never called with no data to send (count ==
0). Thus, the first test on count, at the beginning of the function is
useless and may be removed. This way, by reading the code, it is obvious the
<chn_htx> variable is always defined.

This patch should fix the issue #1085.
