Allow early FB reads to fall back to BAR0 when the VRAM aperture is not ready. This lets SR-IOV VFs consume host-provided init data before requesting full GPU access. For ASICs that support request_init_data, defer full GPU access until after non-GPU early init to shorten the full-access window. Legacy ASICs(before NV12) do not send request_init_data; the host dumps init data only during full GPU access, so keep the original early full-access request path for them.
