Although sparse declares __builtin_bswap*(), it can't actually do
constant folding inside them (yet). As such, things like
switch (protocol) {
case htons(ETH_P_IP):
break;
}
which we do all over the place cause sparse to warn that it expects a
constant instead of a function call.
Disable __HAVE_BUILTIN_BSWAP*__ if __CHECKER__ is defined to avoid this.
