There are two variables that indicate the interrupt type to be used
in the next test execution, "irq_type" as global and test->irq_type.
The global is referenced from pci_endpoint_test_get_irq() to preserve
the current type for ioctl(PCITEST_GET_IRQTYPE).
The type set in this function isn't reflected in the global "irq_type",
so ioctl(PCITEST_GET_IRQTYPE) returns the previous type.
As a result, the wrong type will be displayed in "pcitest" as follows:
# pcitest -i 0
SET IRQ TYPE TO LEGACY: OKAY
# pcitest -I
GET IRQ TYPE: MSI
Fix this issue by propagating the current type to the global "irq_type".
