crypto/arm64: sm3 - Switch to 'ksimd' scoped guard API

Browse source

Switch to the more abstract 'scoped_ksimd()' API, which will be modified
in a future patch to transparently allocate a kernel mode FP/SIMD state
buffer on the stack, so that kernel mode FP/SIMD code remains
preemptible in principle, but without the memory overhead that adds 528
bytes to the size of struct task_struct.
