Subject: [PATCH v3 3/4] PCI/portdrv: Loose the condition check for disabling hotplug interrupts

Currently when 'pcie_ports_native' and host's 'native_pcie_hotplug' are
both false, kernel will not disable PCIe hotplug interrupts. But as
those could be affected by software setup like kernel cmdline parameter,
remove the depency over them.
