trace: module: Maintain a valid user count
The replacement of the 'count' variable by two variables 'incs' and 'decs' to resolve some race conditions during module unloading was done in parallel with some cleanup in the trace subsystem, and was integrated as a merge. Unfortunately, the formula for this replacement was wrong in the tracing code, and the refcount in the traces was not usable as a result. Use 'count = incs - decs' to compute the user count.
