MINOR: quic: do not reject PADDING followed by other frames

It is valid for a QUIC packet to contain a PADDING frame followed by
one or several other frames.

quic_parse_padding_frame() does not require change as it detect properly
the end of the frame with the first non-null byte.

This allow to use quic-go implementation which uses a PADDING-CRYPTO as
the first handshake packet.
