Add missing dtrace return invocations

Some return paths were not going through dtrace
hooks so no function-return probes were being triggered
on dtrace/systemtap.
The return probe will now inform the user of which function
it returns *from* as opposed the previous behaviour of
informing where it returns *to*.
