wifi: iwlwifi: mei: wait for the mac to stop on suspend
When iwlmei driver is removed, it removes all the interfaces
since CSME will take over the NIC while there is no SAP connection.
When the iwlmei driver is removed due to the host being suspended,
this results in the interface being down after resume since the
interface was removed on suspend so mac80211 will not try to bring it
up on resume.
Since on suspend the mac is stopped anyway by mac80211, there is
no need to remove the interface in this case. Wait for the mac
to stop instead. Once the mac is stopped, the driver will not
access the NIC anymore so it is safe for CSME to take over.
