Yu Watanabe 1d30fc5cb6 network: revert previous changes to address_compare_func() 
This partially reverts fe841414ef and
2a236f9fc0.

For IPv4, kernel compares the local address, prefix, and prefixlen.
For IPv6, kernel compares only the local address.
Let's follow the kernel's comparison way.

Fixes #17831.
