History
Ryan Stone 6f6924e5a6 The in-kernel CTF parser caches the result of its first attempt to parse 
CTF data from a module.  On subsequent attempts to retrieve CTF data for
a module, return an error if there no CTF data.

This fixes a panic if you try to enable fbt probes on a module with CTF
data twice.
