x86: Fix kernel-doc atomic.h warnings

Browse source 
Fix kernel-doc warnings in arch/x86/include/asm/atomic.h that are caused by
having a #define macro between the kernel-doc notation and the function
name.  Fixed by moving the #define macro to after the function
implementation.

Make the same change for atomic64_{32,64}.h for consistency even though
there were no kernel-doc warnings found in these header files, but there
would be if they were used in generation of documentation.

Fixes these kernel-doc warnings:

../arch/x86/include/asm/atomic.h:84: warning: Excess function parameter 'i' description in 'arch_atomic_sub_and_test'
../arch/x86/include/asm/atomic.h:84: warning: Excess function parameter 'v' description in 'arch_atomic_sub_and_test'
../arch/x86/include/asm/atomic.h:96: warning: Excess function parameter 'v' description in 'arch_atomic_inc'
../arch/x86/include/asm/atomic.h:109: warning: Excess function parameter 'v' description in 'arch_atomic_dec'
../arch/x86/include/asm/atomic.h:124: warning: Excess function parameter 'v' description in 'arch_atomic_dec_and_test'
../arch/x86/include/asm/atomic.h:138: warning: Excess function parameter 'v' description in 'arch_atomic_inc_and_test'
../arch/x86/include/asm/atomic.h:153: warning: Excess function parameter 'i' description in 'arch_atomic_add_negative'
../arch/x86/include/asm/atomic.h:153: warning: Excess function parameter 'v' description in 'arch_atomic_add_negative'
