Subject: HTTP/2: cleaned up state while closing stream.
X-Git-Tag: release-1.9.12~3
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=8b40f1eaec90be72e791904b345db15f536dca45;p=nginx.git

HTTP/2: cleaned up state while closing stream.

Without this the state might keep pointing to already closed stream.
