PM / core: Fix direct_complete handling for devices with no callbacks
Commit 08810a41 (PM / core: Add NEVER_SKIP and SMART_PREPARE driver flags) inadvertently prevented the power.direct_complete flag from being set for devices without PM callbacks and with disabled runtime PM which also prevents power.direct_complete from being set for their parents. That led to problems including a resume crash on HP ZBook 14u. Restore the previous behavior by causing power.direct_complete to be set for those devices again, but do that in a more direct way to avoid overlooking that case in the future.
