Rafael J. Wysocki a143c36776 PM: runtime: Do not clear needs_force_resume with enabled runtime PM 
commit 359afc8eb0 upstream.

Commit 89d9cec3b1 ("PM: runtime: Clear power.needs_force_resume in
pm_runtime_reinit()") added provisional clearing of power.needs_force_resume
to pm_runtime_reinit(), but it is done unconditionally which is a
mistake because pm_runtime_reinit() may race with driver probing
and removal [1].

To address this, notice that power.needs_force_resume should never
be set when runtime PM is enabled and so it only needs to be cleared
when runtime PM is disabled, and update pm_runtime_init() to only
clear that flag when runtime PM is disabled.

Fixes: 89d9cec3b1 ("PM: runtime: Clear power.needs_force_resume in pm_runtime_reinit()")
