mips: ftrace: fix static function graph tracing
commit 6fb8656646f996d1eef42e6d56203c4915cb9e08 upstream.
ftrace_graph_caller was never run after calling ftrace_trace_function,
breaking the function graph tracer. Fix this, bringing it in line with the
x86 implementation.
While we're at it, also streamline the control flow of _mcount a bit to
reduce the number of branches.
