tracing/ftrace: fix the check on nopped sites
Impact: fix a dynamic tracing failure
Recently, the function and function graph tracers failed to use dynamic
tracing after the following commit:
fa9d13cf135efbd454453a53b6299976bea245a9
(ftrace: don't try to __ftrace_replace_code on !FTRACE_FL_CONVERTED rec)
The patch is right except a mistake on the check for the FTRACE_FL_CONVERTED
flag. The code patching is aborted in case of successfully nopped sites.
What we want is the opposite: ignore the callsites that haven't been nopped.
