ieee1394: limit early node speed to host interface speed
The following patch limits the node speed to the host interface speed,
before using it.

It should actually suffice to do this only for the local node's
speedcap[]. But there is another bug in the speed calculation:
The local node's speed is not correctly propagated to the speeds
which are to be used to access remote nodes.
