iwlwifi: pcie: fix resume when no opmode is present

Browse source 
If no opmode is present during suspend/resume (i.e. if
the iwldvm or iwlmvm isn't loaded) the driver crashes
during resume, trying to call the rfkill notification.
Avoid that, and also don't enable the rfkill interrupt
in this case (to avoid crashing trying to handle the
interrupt later.)
