After commit d42c7891d26e4 ("utils: Do not reset family for default, any,
all addresses"), when call get_addr() for any/all addresses, we will set
addr->flags to ADDRTYPE_INET_UNSPEC if family is AF_INET/AF_INET6, which
makes is_addrtype_inet() checking passed and assigns incorrect address
to kernel. The ip link cmd will return error like:
]# ip link add ipip1 type ipip local any remote 1.1.1.1
RTNETLINK answers: Numerical result out of range
Fix it by using is_addrtype_inet_not_unspec() to avoid unspec addresses.
geneve, vxlan are not affected as they use AF_UNSPEC family when call
get_addr()
