Fiona Ebner 4b7975e75d update submodule and patches to QEMU 8.1.5
Most notable fixes from a Proxmox VE perspective are:

* "virtio-net: correctly copy vnet header when flushing TX"
  To prevent a stack overflow that could lead to leaking parts of the
  QEMU process's memory.
* "hw/pflash: implement update buffer for block writes"
  To prevent an edge case for half-completed writes. This potentially
  affected EFI disks.
* Fixes to i386 emulation and ARM emulation.

No changes for patches were necessary (all are just automatic context
changes).

Subject: [PATCH] PVE: [Config] block/file: change locking default to off
'auto' only checks whether the system generally supports OFD
locks but not whether the storage the file resides on
supports any locking, causing issues with NFS.
