uprobes: guard trace cleanup against error pointers

Browse source

Sashiko pointed out the some of the scope cleanups for free_uprobe
could get an error pointer. Handle this case in free_uprobe
to prevent a crash.

On the other hand the macro doesn't need the guard because
free_uprobe itself already does the check.
