Kishon Vijay Abraham I 8669f20f61 misc: pci_endpoint_test: Avoid using module parameter to determine irqtype ...

commit b2ba9225e0 upstream.

commit e03327122e ("pci_endpoint_test: Add 2 ioctl commands")
uses module parameter 'irqtype' in pci_endpoint_test_set_irq()
to check if IRQ vectors of a particular type (MSI or MSI-X or
LEGACY) is already allocated. However with multi-function devices,
'irqtype' will not correctly reflect the IRQ type of the PCI device.

Fix it here by adding 'irqtype' for each PCI device to show the
IRQ type of a particular PCI device.
