sw64: fix stack trace error 

Sunway inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8CCS9



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

The stack tracer looks for a function that does not match the one stored
on the stack, so cat /sys/kernel/debug/tracing/stack_trace is empty. Fix
it.
