[PATCH, net-next 1/2] bpf: btf: avoid -Wreturn-type warning

[Arnd Bergmann]

gcc warns about a noreturn function possibly returning in
some configurations:

kernel/bpf/btf.c: In function 'env_type_is_resolve_sink':
kernel/bpf/btf.c:729:1: error: control reaches end of non-void function 
[-Werror=return-type]

Using BUG() instead of BUG_ON() avoids that warning and otherwise
does the exact same thing.

Fixes: eb3f595dab40 ("bpf: btf: Validate type reference")
