PM / Sleep: Prevent waiting forever on asynchronous suspend after abort
commit 1f758b23177d588a71b96ad02990e715949bb82f upstream.
__device_suspend() must always send a completion. Otherwise, parent
devices will wait forever.
Commit 1e2ef05b, "PM: Limit race conditions between runtime PM and
system sleep (v2)", introduced a regression by short-circuiting the
complete_all() for certain error cases.
This patch fixes the bug by always signalling a completion.
Addresses http://crosbug.com/31972
Tested by injecting an abort.
