Subject: [PATCH] [posix-app] discard received HDLC frame on error (#3394)

This commit changes the `HdlcInterface::HandleHdlcFrame()` callback
which handles a received and decoded HDLC frame such that it
discards a bad/incorrect frame from the multi frame buffer (i.e,
discard the frame on any error).
