Unlike HTTP/1 transactions, malformed HTTP/2 requests are rejected before HttpSM creation, so they bypassed the normal transaction logging path. That left malformed h2 traffic out of squid.log even when similar h1 failures were visible. This adds a pre-transaction LogAccess path for malformed h2 request headers and emits a best-effort access log entry before resetting the stream. (cherry picked from commit 05554ca)
