fix incorrect usage of errors.Is

errors.Is is supposed to used for equality of errors, not for type
assertions. That's what errors.As is there for.

fix decoding of packet numbers in different packet number spaces
...
When QUIC abandoned the "stream 0" design, it introduced separate
packet number spaces for packets with different encryption levels.
Packet number compression now also works per packet number space.
The current code doesn't lead to any problems if the peer starts sending
with packet number 0, as we only exchange a few packets in the Initial
and the Handshake packet number space and there's nothing to compress.
It might lead to problems if the peer starts with a large packet number
in one space (which is allowed by the spec), and then starts with a
small packet number in another packet number space.

don't queue a packet for later decryption of decryption already failed
...
This was an optimization in gQUIC, which relied on trial decryption. In
IETF QUIC, we know with certainty which keys were used to encrypt a
packet, so if decryption fails once, we are certain it will never
succeed.

CONGESTION_FEEDBACK was reserved for future use in gQUIC, but has never
actually been implemented. It won't make it to IETF QUIC, so we don't
need to check for it. Note that we'd still reject a CONGESTION_FEEDBACK
frame, since we're rejecting any unknown frame type.
