From: Ben Dooks <ben.dooks@codethink.co.uk>

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?

Fixes: dd293df6395a2 ("tracing: Move trace sysctls into trace.c")
