selftests: pci_endpoint: Skip IRQ test if IRQ is out of range.

[ Upstream commit 106fc08b30a2ece49a251b053165a83d41d50fd0 ]

The pci_endpoint_test tests the entire MSI/MSI-X range, which generates
false errors on platforms that do not support the whole range.

Skip the test in such cases and report accordingly.
