iwlwifi: mvm: fix wowlan resume failed to load INIT ucode

If we set disconnect on wowlan and run suspend/resume, will run
into:
...snipped
iwlwifi 0000:01:00.0: Failed to load firmware chunk!
iwlwifi 0000:01:00.0: Could not load the [0] uCode section
iwlwifi 0000:01:00.0: Failed to start INIT ucode: -110
iwlwifi 0000:01:00.0: Failed to run INIT ucode: -110
iwlwifi 0000:01:00.0: Failed to start RT ucode: -110

It is because we still keep IWL_MVM_STATUS_IN_HW_RESTART in
__iwl_mvm_resume.  When mac80211 starts the device as
__iwl_mvm_mac_start(), we will miss iwl_mvm_restart_cleanup(mvm).
