[PATCH v4 3/4] hw/i386/pc: Propagate error if PC_SPEAKER device creation failed

[Philippe Mathieu-Daudé]

In commit 40f8214fcd ("hw/audio/pcspk: Inline pcspk_init()")
we neglected to give a change to the caller to handle failed
device creation cleanly. Here this can not happen because
pc_basic_device_init() uses &error_fatal. Anyhow, do the
proper error reporting to avoid bad code example spreading.
