http2: use original error for cancelling pending streams

Previously, if `session.destroy()` was called with an error object,
the information contained in it would be discarded and a generic
`ERR_HTTP2_STREAM_CANCEL` would be used for all pending streams.

Instead, make the information from the original error object
available.
