When we fail to modify the memory attributes for the VRAM allocation, the allocation - which was made using AllocatePages() - is freed using FreePool(). This is incorrect by itself, but it masks a second bug, i.e., that the address of the allocation is not in VramBaseAddress but in *VramBaseAddress. So fix both issues.
