[PATCH] Fix GO_SLOW delay

This patch changes the delay for the US_FL_GO_SLOW patch from 110us to 125.
Some delays need this extra delay includign Jan De Luyck's drive which spawned
the original increase from 110 to 110us. 125 is a microframe, so this delay
seems to make sense more than just be a random delay (thanks to David Brownell
for pointing that out after my original patch).
