perf sort: Check return value of strdup()

When setup_sorting() is called, 'str' is passed to strtok_r() but it's
not checked to have a valid pointer.  As strtok_r() accepts NULL pointer
on a first argument and use the third argument in that case, it can
cause a trouble since our third argument, tmp, is not initialized.
