BUG/MEDIUM: quic: Crash after QUIC server callbacks restoration (OpenSSL 3.5)

Revert this patch which is no more useful since OpenSSL 3.5.1 to remove the
QUIC server callback restoration after SSL context switch:

    MINOR: quic: OpenSSL 3.5 internal QUIC custom extension for transport parameters reset

It was required for 3.5.0. That said, there was no CI for OpenSSL 3.5 at the date
of this commit. The CI recently revealed that the QUIC server side could crash
during QUIC reg tests just after having restored the callbacks as implemented by
the commit above.

Also revert this commit which is no more useful because it arrived with the commit
above:

	BUG/MEDIUM: quic: SSL/TCP handshake failures with OpenSSL 3.

Must be backported to 3.2.
