PM / Sleep: fix async suspend_late/freeze_late error handling
commit 246ef766743618a7cab059d6c4993270075b173e upstream.
If an asynchronous suspend_late or freeze_late callback fails
during the SUSPEND, FREEZE or QUIESCE phases, we don't propagate the
corresponding error correctly, in effect ignoring the error and
continuing the suspend-to-ram/hibernation. During suspend-to-ram this
could leave some devices without a valid saved context, leading to a
failure to reinitialize them during resume. During hibernation this
could leave some devices active interfeering with the creation /
restoration of the hibernation image. Also this could leave the
corresponding devices without a valid saved context and failure to
reinitialize them during resume.
Fixes: de377b397272 (PM / sleep: Asynchronous threads for suspend_late)
