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.
