base: don't use static array indices for buffer argument of _nl_inet_ntop()
Seems the static array indices can confuse coverity. I think coverity is wrong
here, regardless, change it.
libnl-3.8.0/include/base/nl-base-utils.h:683: overrun-buffer-arg: Overrunning buffer pointed to by "buf" of 16 bytes by passing it to a function which accesses it at byte offset 45 using argument "(addr_family == 2) ? 16 : 46" (which evaluates to 46).
# 681| * and a suitably large buffer, it cannot. Assert for that. */
# 682|
# 683|-> r = (char *)inet_ntop(addr_family, addr, buf,
# 684| (addr_family == AF_INET) ? INET_ADDRSTRLEN :
# 685| INET6_ADDRSTRLEN);
