RISC-V: KVM: Use raw_spinlock for VMID update critical section
87ee18a 
The VMID update critical section performs an IPI broadcast via
on_each_cpu_mask() on VMID version rollover, which must not be preempted
under PREEMPT_RT. Convert vmid_lock to raw_spinlock_t and use plain
raw_spin_lock()/raw_spin_unlock() (interrupts stay enabled, since
on_each_cpu_mask() requires it).
