[PATCH 3/3] selftests: pci_endpoint: Skip doorbell test when unsupported

[Koichiro Den]

PCITEST_DOORBELL may return -EOPNOTSUPP when the endpoint does not
advertise CAP_DYNAMIC_INBOUND_MAPPING.

Treat this like other optional capabilities and skip the doorbell test
instead of reporting a failure.
