vgsp-disp: retry the instance block through guest RAM when the shadow copy is empty
The RM's vidmem writes may use the coherent CPU mapping rather than the
BAR1 aperture, in which case the display instance block lands at the
announced address in guest RAM. Log the source used (src=fb|ram) and
fall back to vfio_dma_rw before reporting the hash table empty.
