tracing: Avoid -Wformat-nonliteral warning
Building with -Wformat-nonliteral, gcc complains kernel/trace/trace_output.c: In function ‘seq_print_sym’: kernel/trace/trace_output.c:356:3: warning: format not a string literal, argument types not checked [-Wformat-nonliteral] trace_seq_printf(s, fmt, name); But seq_print_sym only has a single caller which passes "%s" as fmt, so we might as well just use that directly. That also paves the way for further cleanups that will actually make that format string go away entirely.
