[RFC] Don'd hold work_sem while calling worker functions

[Richard Weinberger]

I fail to see why we need work_sem while wrk->func() is executed.
Artem, do you have an idea?

Having the wear_leveling_worker() called without work_sem held
would simplify the fastmap code too. I'm currently reworking some
of it's code and I'm in locking hell. 8-)

Thanks,
