BUILD: quic: Fix build error when building QUIC against wolfssl.

This commit:

    "MINOR: quic: Enable early data at SSL session level (aws-lc)

introduced a build error when using wolfssl as TLS stack
because it references unknown function wolfSSL_set_quic_early_data_enabled()
which is not defined in qc_set_quic_early_data_context() that must not be used
in this case. The compilation of this fonction was enabled for wolfssl when
it should not have by the mentionned commit.

No backport is needed.
