append a unique number to the device name.
Fixes v4l2-compliance:
Media Controller ioctls:
fail: v4l2-test-media.cpp(205): v2_entity_names_set.find(key) != v2_entity_names_set.end()
test MEDIA_IOC_G_TOPOLOGY: FAIL
fail: v4l2-test-media.cpp(394): num_data_links != num_links
test MEDIA_IOC_ENUM_ENTITIES/LINKS: FAIL
