[Qemu-devel] [PATCH v3 7/8] hw/pcie: AER and hot-plug events must use device's interrupt

[Marcel Apfelbaum <marcel.a@redhat.com>]

The fields hpev_intx and aer_intx were removed because
both AER and hot-plug events must use device's interrupt.
Assert/deassert interrupts using pci irq wrappers instead.

Signed-off-by: Marcel Apfelbaum <marcel.a@redhat.com>

Changes from v2:
 - Addressed Alex Williamson's comments
   - replaced calls to pci_set_irq with
     pci_irq_assert/deassert when possible
