cpu/SMT: Fix cpu_smt_possible() comment

Browse Source 
Commit e1572f1d08 ("cpu/SMT: create and export cpu_smt_possible()")
introduces cpu_smt_possible() to represent if SMT is theoretically
possible. It returns true when SMT is supported and not forcefully
disabled ('nosmt=force'). But the comment of it says "Returns true if
SMT is not supported of forcefully (irreversibly) disabled", which is
wrong. Fix that comment accordingly.
