wifi(implementation): Fix spammy log

wifi.interface.0, etc should only be checked if the primary property
used on most devices (wifi.interface & wifi.concurrent.interface) does
not exist.

wifi.interface.0, etc should only defined on Android auto platforms.

Bug: 126925255
Test: Manually verified that the spammy log does not exist
