Subject: [PATCH 3/6] apr: make remove callback of apr driver void returned

Since commit fc7a6209d571 ("bus: Make remove callback return
void") forces bus_type::remove be void-returned, it doesn't
make much sense for any bus based driver implementing remove
callbalk to return non-void to its caller.

This change is for apr bus based drivers.
