locking/atomic/x86: Use ALT_OUTPUT_SP() for __alternative_atomic64()
[ Upstream commit 8b64db9733c2e4d30fd068d0b9dcef7b4424b035 ]
CONFIG_X86_CMPXCHG64 variant of x86_32 __alternative_atomic64()
macro uses CALL instruction inside asm statement. Use
ALT_OUTPUT_SP() macro to add required dependence on %esp register.
