Jiri Olsa 6b95cc562d ftrace: Fix direct_functions leak in update_ftrace_direct_del 
Alexei reported memory leak in update_ftrace_direct_del.
We miss cleanup of the replaced direct_functions in the
success path in update_ftrace_direct_del, adding that.

Fixes: 8d2c1233f3 ("ftrace: Add update_ftrace_direct_del function")
