annotate src/http/v2/ngx_http_v2.c @ 7618:8a7b59347401

HTTP/2: removed ngx_debug_point() call. With the recent change to prevent frames flood in d4448892a294, nginx will finalize the connection with NGX_HTTP_V2_INTERNAL_ERROR whenever flood is detected, causing nginx aborting or stopping if the debug_points directive is used in nginx config.
