Masami Hiramatsu (Google) 2bc56fdae1 ftrace: Add ftrace_get_symaddr to convert fentry_ip to symaddr ...

This introduces ftrace_get_symaddr() which tries to convert fentry_ip
passed by ftrace or fgraph callback to symaddr without calling
kallsyms API. It returns the symbol address or 0 if it fails to
convert it.
