Subject: drm/vmwgfx: Remove primary memory validation against mode while
creating fb
Git-commit: 018f60b26602bb41b33139da3408224e36dfe02d
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
This validation is not required because user-space will send create_fb
request once the memory is allocated. This check should be performed
during mode-setting.
