s390/spinlock: cleanup spinlock code
Improve the spinlock code in several aspects:
- Have _raw_compare_and_swap return true if the operation has been
successful instead of returning the old value.
- Remove the "volatile" from arch_spinlock_t and arch_rwlock_t
- Rename 'owner_cpu' to 'lock'
- Add helper functions arch_spin_trylock_once / arch_spin_tryrelease_once
