m68k: Avoid xchg() warning
gcc warns about the value of xchg()/cmpxchg() being unused
in some cases:
net/core/filter.c: In function 'bpf_clear_redirect_map':
arch/m68k/include/asm/cmpxchg.h:137:3: warning: value computed is not used [-Wunused-value]
106 | #define cmpxchg(ptr, o, n) cmpxchg_local((ptr), (o), (n))
net/core/filter.c:3595:4: note: in expansion of macro 'cmpxchg'
3595 | cmpxchg(&ri->map, map, NULL);
Shut up that warning like we do on other architectures, by
turning the macro into a statement expression.
