qemu: fix CVE-2023-3019

Browse Source 
A DMA reentrancy issue leading to a use-after-free error
was found in the e1000e NIC emulation code in QEMU. This
issue could allow a privileged guest user to crash the
QEMU process on the host, resulting in a denial of service.

CVE-2023-3019-0002 is the CVE fix and CVE-2023-3019-0001
is dependent CVE fix.

fix indent issue in qemu.inc file.

CVE-2023-3019 patch required Mem ReenttranceyGuard structure
definition, it's defined in commit:
a2e1753b80
but the patch is causing errors:
Failed: qemux86 does not shutdown within timeout(120)
so backported only required structure definition.

Subject: [PATCH] net: Provide MemReentrancyGuard * to qemu_new_nic()
Recently MemReentrancyGuard was added to DeviceState to record that the
device is engaging in I/O. The network device backend needs to update it
when delivering a packet to a device.
In preparation for such a change, add MemReentrancyGuard * as a
parameter of qemu_new_nic().

From 3c0463a650008aec7de29cf84540652730510921 Mon Sep 17 00:00:00 2001
From: Akihiko Odaki <akihiko.odaki@daynix.com>
Date: Thu, 1 Jun 2023 12:18:59 +0900
Subject: [PATCH] net: Update MemReentrancyGuard for NIC
Recently MemReentrancyGuard was added to DeviceState to record that the
device is engaging in I/O. The network device backend needs to update it
when delivering a packet to a device.
This implementation follows what bottom half does, but it does not add
a tracepoint for the case that the network device backend started
delivering a packet to a device which is already engaging in I/O. This
is because such reentrancy frequently happens for
qemu_flush_queued_packets() and is insignificant.
Fixes: CVE-2023-3019
