xlate: use const struct in6_addr in linklocal check
Commit 83c2757bd16e ("xlate: Move tnl_neigh_snoop() to
terminate_native_tunnel()") introduced a call to
IN6_IS_ADDR_MC_LINKLOCAL() when checking neighbor discovery.
The call to this assumes that the argument may be a const uint8_t *.
According to The Open Group Base Specifications Issue 7, 2018:
macro is of type int and takes a single argument of
type const struct in6_addr *
The GNU implementation allows a bit of flexibility, by internally
casting the argument. However, other implementations (such as OS X)
more rigidly implement the standard and fail with errors like:
error: member reference base type 'const uint8_t'
(aka 'const unsigned char') is not a structure or union
