bus_generic_detach: Delete children after detaching them

This provides better semantics as a standalone DEVMETHOD for
device_attach as bus drivers should remove child devices they created
as part of detach cleanup. The implementation calls
bus_detach_children() first to permit child devices an opportunity to
veto the detach operation. If that succeeds, device_delete_children()
is used to delete the child devices.

This requires fixing various drivers that were deleting devices
explicitly (via a device_t pointer cached in the softc) after calling
bus_generic_detach to stop doing that and just rely on
bus_generic_detach to remove child devices.

Check for errors when detaching children first, not last

These detach routines in these drivers all ended with 'return
(bus_generic_detach())' meaning that if any child device failed to
detach, the parent driver was left in a mostly destroyed state, but
still marked attached. Instead, bus drivers should detach child
drivers first and return errors before destroying driver state in the
parent.
