bpf: Embed kernel CONFIG check into the if statement in bpf_setsockopt
This patch moves the "#ifdef CONFIG_XXX" check into the "if/else"
statement itself. The change is done for the bpf_setsockopt()
function only. It will make the latter patches easier to follow
without the surrounding ifdef macro.
