fgraph: Make fgraph_no_sleep_time signed

Browse source

The variable fgraph_no_sleep_time changed from being a boolean to being a
counter. A check is made to make sure that it never goes below zero. But
the variable being unsigned makes the check always fail even if it does go
below zero.

Make the variable a signed int so that checking it going below zero still
works.
