x86[-64]:Remove 'volatile' from atomic_t

Browse Source 
Any code that relies on the volatile would be a bug waiting to happen
anyway.

Don't encourage people to think that putting 'volatile' on data
structures somehow fixes problems.  We should always use proper locking
(and other serialization) techniques.
