crypto: hisilicon - replace 'smp_processor_id' with the raw version of the macro

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8WJ1D


CVE: NA

--------------------------------------------------------

smp_processor_id() is unsafe if it's used in a preemption-on critical
section. It will cause the calltrace when the preemption-on and sets the
CONFIG_DEBUG_PREEMPT. So replace 'smp_processor_id' with the raw version
in preemptible to avoid the following calltrace:
