Increase duration before DPB marks a port frozen

[Kurt Mosiejczuk]

With the default of 10 seconds with no response, my DPB status screen
stays almost entirely red for the duration of the sparc64 bulk.

Increasing it to 45 seconds tends to eliminate the red except for things
that are actually stuck... and rust ports. :)

How would folks feel about increasing to 45 seconds?
