BUG/MINOR: mux-quic: do not send too big MAX_STREAMS ID

QUIC stream IDs are expressed as QUIC variable integer which cover the
range for 0 to 2^62 - 1. As such, it is forbidden to send an ID for
MAX_STREAMS flow-control frame which would allow to overcome this value.

This patch fixes MAX_STREAMS emission to ensure sent value is valid.
This also ensures that the peer cannot open a stream with an invalid ID
as this would cause a flow-control violation instead.

This must be backported up to 2.6.
