--------------------------------

commit e92eb246 upstream.

debug_active_activate() expected ref->count to be zero
which is not true anymore as __i915_active_activate() calls
debug_active_activate() after incrementing the count.

v2: No need to check for "ref->count == 1" as __i915_active_activate()
already make sure of that(Janusz).
