gnutls_session_get_data2: fix operation without a timeout callback
When TLS1.3 was introduced, gnutls_session_get_data2 was modified
to assume that the callbacks set included the timeout one which was
not previously necessary except for some special cases. This corrects
that issue and makes sure that gnutls_session_get_data2() does not
fail (but not necessarily succeed), if that timeout callback is not
set.
Resolves: #823
