locking/arch: Avoid variable shadowing in local_try_cmpxchg()

Browse source

[ Upstream commit d6b45484c1 ]

Several architectures define arch_try_local_cmpxchg macro using
internal temporary variables named ___old, __old or _old. Remove
temporary varible in local_try_cmpxchg to avoid variable shadowing.

No functional change intended.
