Bang Li c6ed4d84a2 ARC: remove redundant READ_ONCE() in cmpxchg loop

This patch reverts commit 7082a29c22 ("ARC: use ACCESS_ONCE in cmpxchg
loop").

It is not necessary to use READ_ONCE() because cmpxchg contains barrier. We
can get it from commit d57f727264 ("ARC: add compiler barrier to LLSC
based cmpxchg").
