Event pipe: disabled c->read->available checking for SSL.

In SSL connections, data can be buffered by the SSL layer, and it is
wrong to avoid doing c->recv_chain() if c->read->available is 0 and
c->read->pending_eof is set.  And tests show that the optimization in
question indeed can result in incorrect detection of premature connection
close if upstream closes the connection without sending a close notify
alert at the same time.  Fix is to disable c->read->available optimization
for SSL connections.
