Re: [PATCH v4] netlink: Return prefix length for IPv6 addresses in nl_addr_get()

nl_addr_get() was not setting the prefix_len output parameter for IPv6 addresses, only for IPv4. This meant callers always got 0 for IPv6, forcing them to use a hardcoded default (64).

Fix by assigning *prefix_len even in the IPv6 case.
