Maya Erez 3161adddf3 wil6210: prevent access to 11AD device if resume fails 
In case wil6210 resume fails, wil6210 suspend function will try
to access the suspended device in the next kernel suspend.
To prevent that, add wil_status_suspended flag to indicate if the
device is already suspended and clear it only if the resume succeeds.
