pmdomain: core: Don't clear suspended_count at genpd_prepare()

There is no longer any need to clear genpd->suspended_count in
genpd_prepare(), as it should be correctly incremented and decremented for
all cases. In fact, if the counter isn't correctly managed we would be
hiding a problem that we shouldn't. Therefore, let's not clear it.
