x86/sysfb: Fix check for bad VRAM size [ Upstream commit dacc9092336be20b01642afe1a51720b31f60369 ] When checking whether the reported lfb_size makes sense, the height * stride result is page-aligned before seeing whether it exceeds the reported size. This doesn't work if height * stride is not an exact number of pages. For example, as reported in the kernel bugzilla below, an 800x600x32 EFI framebuffer gets skipped because of this. Move the PAGE_ALIGN to after the check vs size.
