MINOR: connection: make conn_stream users also check for per-stream error flag
In a 1:1 connection:stream there's no problem relying on the connection
flags alone to check for errors. But in a mux, it will be possible to mark
certain streams in error without having to mark all of them. An example is
an H2 client sending RST_STREAM frames to abort a long download, or a parse
error requiring to abort only this specific stream.
This commit ensures that stream-interface and checks properly check for
CS_FL_ERROR in cs->flags wherever CO_FL_ERROR was in use. Most likely over
the long term, any check for CO_FL_ERROR will have to disappear.
