Greentime Hu 0cde56e028 nds32: Fix a kernel panic issue because of wrong frame pointer access. 
It can make sure that trace_hardirqs_off/trace_hardirqs_on can get a correct
return address by frame pointer through __builtin_return_address() in this fix.

Unable to handle kernel paging request at virtual address fffffffc
pgd = 3c42e9cf
