[Stable-7.2.10 32/33] ui/console: Fix console resize with placeholder su

Subject: [Stable-7.2.10 32/33] ui/console: Fix console resize with placeholder surface
Date: Thu, 22 Feb 2024 00:47:15 +0300

From: Tianlan Zhou <bobby825@126.com>

In `qemu_console_resize()`, the old surface of the console is keeped 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),
the surface won't be replace.
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.
