David McKay 6e007fac81 asm-generic: Fix 32 bit __generic_cmpxchg_local 
[ Upstream commit d93cca2f3109f88c94a32d3322ec8b2854a9c339 ]

Commit 656e9007ef58 ("asm-generic: avoid __generic_cmpxchg_local
warnings") introduced a typo that means the code is incorrect for 32 bit
values. It will work fine for postive numbers, but will fail for
negative numbers on a system where longs are 64 bit.

Fixes: 656e9007ef58 ("asm-generic: avoid __generic_cmpxchg_local warnings")
