David Gibson 4f01a63779 sysbus: Remove ignored return value of FindSysbusDeviceFunc
Functions of type FindSysbusDeviceFunc currently return an integer.
However, this return value is always ignored by the caller in
find_sysbus_device().

This changes the function type to return void, to avoid confusion over
the function semantics.
