after use spdy keepalive_timeout always 180000

[bin tom]

I add some debug in ngx_http_spdy_module.c

it output

nginx: ngx_conf_merge_msec_value conf -1 prev -1 NGX_CONF_UNSET_MSEC -1 default 30000
nginx: ngx_conf_merge_msec_value conf -1 prev -1 NGX_CONF_UNSET_MSEC -1 default 180000

The 180 seconds timeout is correct for the config provided.
