arm64: cmpxchg: update macros to prevent warnings
Make sure the value we are going to return is referenced in order to
avoid warnings from newer GCCs such as:
arch/arm64/include/asm/cmpxchg.h:162:3: warning: value computed is not used [-Wunused-value]
((__typeof__(*(ptr)))__cmpxchg_mb((ptr), \
^
net/netfilter/nf_conntrack_core.c:674:2: note: in expansion of macro ‘cmpxchg’
cmpxchg(&nf_conntrack_hash_rnd, 0, rand);
[Modified to use the current underlying implementation as current
mainline for both cmpxchg() and cmpxchg_local() does -- broonie]
