[PATCH v1] driver:core: no need to invert the return value of the call_driver_probe()

[Lizhe]

If drv->probe() or drv->bus->probe() returns EPROBE_DEFER,
then there is no need to invert the sign. Similarly,
if it returns -EPROBE_DEFER, no sign inversion is needed either

In the probe function (either bus->probe() or drv->probe()),
there is no return value of EPROBE_DEFER.
