Arnd Bergmann 44472d1b83 atomic: Skip alignment check for try_cmpxchg() old arg ...

The 'old' argument in atomic_try_cmpxchg() and related functions is a
pointer to a normal non-atomic integer number, which does not require
to be naturally aligned, unlike the atomic_t/atomic64_t types themselves.

In order to add an alignment check with CONFIG_DEBUG_ATOMIC into the
normal instrument_atomic_read_write() helper, change this check to use
the non-atomic instrument_read_write(), the same way that was done
earlier for try_cmpxchg() in commit ec570320b0 ("locking/atomic:
Correct (cmp)xchg() instrumentation").

This prevents warnings on m68k calling the 32-bit atomic_try_cmpxchg()
with 16-bit aligned arguments as well as several more architectures
including x86-32 when calling atomic64_try_cmpxchg() with 32-bit
aligned u64 arguments.
