We already call remove_conflicting_framebuffers() on PCI BAR0 during
pci-probe, no need to do that again during device loading.

This avoids calling into remove_conflicting_framebuffers() from within DRM
->load() callback, which might deadlock, once we make this call remove
DRM-backed sysfb-devices, too.
