ftrace: Move record update for normal and modules into a separate function

The updating of a function record is moved to a single function. This will allow
us to add specific changes in one location for both modules and kernel
functions.

Later patches will determine if the function record itself needs to be updated
(which enables the mcount caller), or just the ftrace_ops needs the update.
