misc: pci_endpoint_test: Skip IRQ tests if irq is out of range

Browse source

[ Upstream commit cc8e391067 ]

The pci_endpoint_test tests the 32-bit MSI range. However, the device might
not have all vectors configured. For example, if msi_interrupts is 8 in the
ep function space or if the MSI Multiple Message Capable value is
configured as 4 (maximum 16 vectors).

In this case, do not attempt to run the test to avoid timeouts and directly
return the error value.
