rust: helpers: Avoid raw_spin_lock initialization for PREEMPT_RT
When PREEMPT_RT=y, spin locks are mapped to rt_mutex types, so using
spinlock_check() + __raw_spin_lock_init() to initialize spin locks is
incorrect, and would cause build errors.
Introduce __spin_lock_init() to initialize a spin lock with lockdep
rquired information for PREEMPT_RT builds, and use it in the Rust
helper.
Fixes: d2d6422f8bd1 ("x86: Allow to enable PREEMPT_RT.")
