Steven Rostedt (Google) fd3dc56253 ftrace/x86: Add back ftrace_expected for ftrace bug reports 
After someone reported a bug report with a failed modification due to the
expected value not matching what was found, it came to my attention that
the ftrace_expected is no longer set when that happens. This makes for
debugging the issue a bit more difficult.

Set ftrace_expected to the expected code before calling ftrace_bug, so
that it shows what was expected and why it failed.
