hw/i386/pc: Ensure vmport prerequisites are fulfilled
Since commit 4ccd5fe22feb95137d325f422016a6473541fe9f ('pc: add option to disable PS/2 mouse/keyboard'), the vmport will not be created unless the i8042 PS/2 controller is enabled. To avoid confusion, let's fail if vmport was explicitly requested, but the i8042 controller is disabled. This also changes the behavior of vmport=auto to take i8042 controller availability into account.
