[ Upstream commit 5c2e7736e20d9b348a44cafbfa639fe2653fbc34 ] 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: d2d6422f ("x86: Allow to enable PREEMPT_RT.")
