Bug Description
== SRU Justification ==
[Impact]
When iwlwifi firmware causes the WiFi NIC dropped off PCI bus on system
resume, NULL pointer dereference occurs and the system stops working.
[Fix]
Rescan the bus in order to reprobe the device to avoid mac80211 layer
gets messed up.
[Test]
With the fix in place, system keeps working after firmware issue occurs.
Verified with thousand times of suspend.
[Where problems could occur]
If the firmware/hardware is really dead and beyond recoverable, the same
process can be triggered again and again.
