misc: pci_endpoint_test: Fix displaying 'irq_type' after 'request_irq' error

There are two variables that indicate the interrupt type to be used
in the next test execution, global "irq_type" and "test->irq_type".

The former is referenced from pci_endpoint_test_get_irq() to preserve
the current type for ioctl(PCITEST_GET_IRQTYPE).

In the pci_endpoint_test_request_irq(), since this global variable
is referenced when an error occurs, the unintended error message is
displayed.

For example, after running "pcitest -i 2", the following message
shows "MSI 3" even if the current IRQ type becomes "MSI-X":

  pci-endpoint-test 0000:01:00.0: Failed to request IRQ 30 for MSI 3
  SET IRQ TYPE TO MSI-X:          NOT OKAY

Fix this issue by using "test->irq_type" instead of global "irq_type".
