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.
