We want to be able to call virt data exchange conditionally
after gmc sw init to reserve bad pages as early as possible.
Since this is a conditional call, we will need to call
it again unconditionally later in the init sequence.
Refactor the data exchange function so it can be
called multiple times without re-initializing the work item.
