I do not see any possibility of that other than doing ->remove_interface without previous ->add_interface, but I do not see how that possible. Does crash happen on any suspend or on second one ? I'm attaching patch, which should prevent crash (but not fix the issue, just workaround it), plese apply it. If it make suspend work, please then reload iwlwifi module with debug=0x3 option, suspend/resume machine and provide dmesg output after that.
