[PULL 23/39] hw/timer/sse-timer: Propagate eventual error in sse_timer_realize()

[Peter Maydell]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

If the SSECounter link is absent, we set an error message
in sse_timer_realize() but forgot to propagate this error.
Add the missing 'return'.

Fixes: CID 1450755 (Null pointer dereferences)
