[DCCP]: Use maximum-RTO backoff from DCCP spec
This removes another Fixme, using the TCP maximum RTO rather than the value
specified by the DCCP specification. Across the sections in RFC 4340, 64
seconds is consistently suggested as maximum RTO backoff value; and this is
the value which is now used.
I have checked both termination cases for retransmissions of Close/CloseReq:
with the default value 15 of `retries2', and an initial icsk_retransmit = 0,
it takes about 614 seconds to declare a non-responding peer as dead, after
which the final terminating Reset is sent. With the TCP maximum RTO value of
120 seconds it takes (as might be expected) almost twice as long, about 23
minutes.
