Drivers: hv: util: Don't force error code to ENODEV in util_probe()

If the util_init function call in util_probe() returns an error code,
util_probe() always return ENODEV, and the error code from the util_init
function is lost. The error message output in the caller, vmbus_probe(),
doesn't show the real error code.

Fix this by just returning the error code from the util_init function.
There doesn't seem to be a reason to force ENODEV, as other errors
such as ENOMEM can already be returned from util_probe(). And the
code in call_driver_probe() implies that ENODEV should mean that a
matching driver wasn't found, which is not the case here.
