locking/atomic/x86: Use ALT_OUTPUT_SP() for __arch_{,try_}cmpxchg64_emu()
[ Upstream commit 25cf4fbb596d730476afcc0fb87a9d708db14078 ]
x86_32 __arch_{,try_}cmpxchg64_emu()() macros use CALL instruction
inside asm statement. Use ALT_OUTPUT_SP() macro to add required
dependence on %esp register.
Fixes: 79e1dd05d1a2 ("x86: Provide an alternative() based cmpxchg64()")
