The return value was silently ignored, and not propagated to the caller.

Found by Linux Verification Center (linuxtesting.org) with the SVACE
static analysis tool.

I'm not familiar enough with the code to know if there's anything we
have to undo here in case qed_init_run returns an error. Any additional
comments are appreciated.
