sh: fix format string bug in stack tracer
Kees reported the following error:
arch/sh/kernel/dumpstack.c: In function 'print_trace_address':
arch/sh/kernel/dumpstack.c:118:2: error: format not a string literal and no format arguments [-Werror=format-security]
Use the "%s" format so that it's impossible to interpret 'data' as a
format string.
