Drivers: hv: Make remove callback of hyperv 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.
As such, change the remove function for Hyper-V VMBus based
drivers to return void.
