PM / Sleep: call early resume handlers when suspend_noirq fails
commit 064b021fbe470ecc9ca10f9f87af48c0fc0865fb upstream.
Commit cf579dfb82550e34de7ccf3ef090d8b834ccd3a9 (PM / Sleep: Introduce
"late suspend" and "early resume" of devices) introduced a bug where
suspend_late handlers would be called, but if dpm_suspend_noirq returned
an error the early_resume handlers would never be called. All devices
would end up on the dpm_late_early_list, and would never be resumed
again.
Fix it by calling dpm_resume_early when dpm_suspend_noirq returns
an error.
