On the resize attempt failing with -EINVAL, instead report an informational
message indicating that the requested BAR size is not listed as supported by
the VBIOS.
Without this, as I have an RX 5600 XT which lists only 256MB, 512MB and
1024MB as supported, I see
[drm:amdgpu_device_resize_fb_bar] *ERROR* Problem resizing BAR0 (-22).
