[Qemu-devel] [PATCH] vga: squash build error in vga_update_memory_access()

[Avi Kivity <avi@redhat.com>]

Newer gcc complains that base and size may be used uninitialized, even though
it is clearly a false warning.  Silence the warning by indicating to gcc that
the code path triggering the warning cannot happen.
