The backtrace looked interesting to me, so I checked the code.

It looks like iwl_pci_down() badly needs to be merged with
iwl_pci_remove().  iwl_pci_down() is only called from iwl_pci_remove(),
and is struggles badly to get the data that iwl_pci_remove() already
has.  That may fix everything.  Unfortunately, I have no hardware to
test it.

pci_bus->pci_dev that iwl_pci_down() passes to pci_disable_msi() should
be the same as pdev in iwl_pci_remove().  And pdev should be valid
throughout the function.

Also, the use of the void pointer in iwl_pci_remove() seems
unjustified.  Specific pointers are always better.
