[PVE-User] No keyboard in guest when using mouse/keyboard while the guest boots

Currently, qemu's implementation of i8042 controller is broken (probably
some BIOS issue) - if you type on the keyboard / move mouse while the
guest boots, Linux guest will boot without keyboard.
The core of the problem is: qemu's i8042 buffer (256 characters) will
get full, and Linux i8042 controller initialization will not be able to
empty this buffer, as it assumes i8042 controller has a 16 characters
The cause was more or less identified in "i8042.c: No controller found"
thread on qemu-devel list; a workaround is to decrease "PS2_QUEUE_SIZE
256" to "PS2_QUEUE_SIZE 15".
The fix is not in upstream qemu yet, but I would be glad if it was
integrated in Proxmox VE, as currently, my Linux guests (didn't try with
Windows) almost always loose its keyboard as I reboot them and have VNC
and the rest of the thread.
