u64_stats: Streamline the implementation
The u64 stats code handles 3 different cases:
- 32bit UP
- 32bit SMP
- 64bit
with an unreadable #ifdef maze, which was recently expanded with PREEMPT_RT
conditionals.
Reduce it to two cases (32bit and 64bit) and drop the optimization for
32bit UP as suggested by Linus.
Use the new preempt_disable/enable_nested() helpers to get rid of the
CONFIG_PREEMPT_RT conditionals.
