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.
== Original bug report ==
During the jammy-hwe migration test, I found some machines failed to run the
pm-graph.

One of machine when I rerun it locally, it passed, but others are
still failed.
Following are the machines failed to run pm-graph.
