Subject: [PATCH] trace: ftrace_dump_on_oops[] is not exported, make it static

The ftrace_dump_on_oops string is not used outside of trace.c so
make it static to avoid the export warning from sparse:

kernel/trace/trace.c:141:6: warning: symbol 'ftrace_dump_on_oops' was not declared. Should it be static?
