IB/core: Remove unneeded kobject_get/put calls
The ib_core module will call kobject_get on the parent object of each kobject it creates. This is redundant since kobject_add does that anyway. As a side effect, this patch should fix leaking the ports kobject and the device kobject during unregister flow, since the previous code didn't seem to take into account the kobject_get calls on behalf of the child kobjects.
