Avoid loading of a dynamic engine twice

Avoid loading of a dynamic engine twice

Use the address of the bind function as a DYNAMIC_ID,
since the true name of the engine is not known
before the bind function returns,
but invoking the bind function before the engine
is unloaded results in memory corruption.
