PCI/portdrv: Remove warning about invalid IRQ for hot-added PCIe ports
For hot-added PCIe ports on x86 platforms, we always warned about an
invalid IRQ, e.g.,
pci 0000:00:00.0: device [8086:0e0b] has invalid IRQ; check vendor BIOS
This was because we check pci_dev->irq before actually allocating the IRQ
for the device, which happens in this path:
pcie_port_device_register
pci_enable_device
pci_enable_device_flags
do_pci_enable_device
pcibios_enable_device (on x86)
pcibios_enable_irq
This warning message isn't generated for PCIe ports present at boot time
because x86 arch code has called acpi_pci_irq_enable() in pci_acpi_init()
for each PCI device for safety.
