In `qemu_console_resize()`, the old surface of the console is kept if
the new console size is the same as the old one. If the old surface is a
placeholder, and the new size of console is the same as the placeholder
surface (640*480), it won't be replaced.
In this situation, the surface's `QEMU_PLACEHOLDER_FLAG` flag is still
set, so the console won't be displayed in SDL display mode.
This patch fixes this problem by forcing a new surface if the old one is
a placeholder.
