Currently if the kernel has the intel_iommu=on parameter set, on some platforms removing the driver causes a system reboot. In initialization we associate the control queue interrupts with the pf->hw_oicr_idx and enable the interrupts by setting the CAUSE_ENA bit. The problem comes on teardown because we are not clearing the CAUSE_ENA bit for the control queues, but the vector at pf->hw_oicr_idx (miscellaneous interrupt vector) gets disabled. Fix this by clearing the CAUSE_ENA bit in the appropriate control queue registers on when freeing the miscellaneous interrupt vector. Also, move the call to ice_free_irq_msix_misc() to after ice_deinit_sw() in ice_remove() because ice_deinit_sw() makes an AQ call, but ice_free_irq_msix_misc() disables the miscellaneous vector and it's associated interrupts. Also, create two small helper functions to enable and disable the control queue interrupts respectively.
