Johannes Berg 23aeea943b iwlwifi: pcie: fix another RF-kill race 
When resuming, it's possible for the following scenario to occur:

 * iwl_pci_resume() enables the RF-kill interrupt
 * iwl_pci_resume() reads the RF-kill state (e.g. to 'radio enabled')
 * RF_KILL interrupt triggers, and iwl_pcie_irq_handler() reads the
   state, now 'radio disabled', and acquires the &trans_pcie->mutex.
 * iwl_pcie_irq_handler() further calls iwl_trans_pcie_rf_kill() to
   indicate to the higher layers that the radio is now disabled (and
   stops the device while at it)
 * iwl_pcie_irq_handler() drops the mutex
 * iwl_pci_resume() continues, acquires the mutex and calls the higher
   layers to indicate that the radio is enabled.

At this point, the device is stopped but the higher layers think it's
available, and can call deeply into the driver to try to enable it.
However, this will fail since the device is actually disabled.
