iwlwifi: mei: clear the ownership when the driver goes down
When the driver is unregistered, CSME will take ownership on the
device. Reflect this in the iwlmei object so that we will remember
to re-ask for ownership when the driver will register again.
Not doing so will cause CSME not to give the host ownership and
we will see the following error message when trying to bring up
the interface:
