simplify tls1_process_ticket() exit path
tls1_process_ticket() - the only caller of tls_decrypt_ticket() - ends
in a switch over the return value of tls_decrypt_ticket() to decide
whether or not to set s->internal->tlsext_ticket_expected = 1.
Since tls_decrypt_ticket() already knows what it will return and
partly bases its decision on what to return on whether or not the
ticket needs to be renewed, it can also take care of setting this flag.
This way we don't need to have a confusing switch that conflates some
return values and sets this flag. Moreover, we can get rid of the ugly
TLS1_TICKET_DECRYPTED_RENEW whose only purpose is to signal that the
flag should be set.
