[PATCH] staging: greybus: vibrator: return device_create() errors

[Alfie Varghese]

gb_vibrator_probe() maps any device_create() failure to -EINVAL. This
loses the real errno returned by the driver core, such as -ENOMEM, and
makes probe failures harder to diagnose correctly.

Return PTR_ERR(dev) instead so callers receive the actual failure reason
while preserving the existing cleanup path.
