Callback function invoked by Session.recv when an
invalid non-DATA frame is received. The |error_code| indicates the
error. It is usually one of the FrameError but
that is not guaranteed. When this callback function is invoked,
the library automatically submits either RST_STREAM or GOAWAY
frame.
If frame is HEADERS or PUSH_PROMISE, the `hfa`
member of thee data structure is always `null`
