drm/amdgpu: Separate vf2pf work item init from virt data exchange

Browse Source 
[ Upstream commit 892deb48269c65376f3eeb5b4c032ff2c2979bd7 ]

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.

v2: Cleaned up the code. Kept the original call to init_exchange_data()
inside early init to initialize the work item, afterwards call
exchange_data() when needed.
