Cleans up after an interruptible wait: waits for any pending invocations of the callback previously registered with vlc_interrupt_prepare(), and rechecks for any pending interruption.

Warning: As this function waits for ongoing callback invocation to complete, the caller must not hold any resource necessary for the callback to run. Otherwise a deadlock may occur.
