tls: don't call gnutls_deinit() after failed gnutls_init()

Browse Source 
Don't assume gnutls_init() leaves the session pointer at NULL when it
returns with an error status. It might be a session that was already
allocated and then freed without resetting it to NULL after an error.

Fixes: 3e32e7e694 ("tls: move gnutls code into tls_gnutls.c")
