PCI: pciehp: Ignore interrupts during D3cold
If a hotplug port is suspended to D3cold, its slot status register cannot
be read. If that hotplug port happens to share its IRQ with other devices,
whenever an interrupt occurs for one of these devices, pciehp logs a
"no response from device" message and tries to read the PCI_EXP_SLTSTA
register, even though we know that will fail.
Ignore interrupts while we're in D3cold.
