PM: runtime: Convert pm_runtime_blocked() to static inline
The comment in pm_runtime_blocked() is acutally wrong: power.last_status
is not a bit field. Its data type is an enum and so one can reasonably
assume that partial updates of it will not be observed.
Accordingly, pm_runtime_blocked() can be converted to a static inline
function and the related locking overhead can be eliminated, so long
as it is only used in system suspend/resume code paths because
power.last_status is not expected to be updated concurrently while
that code is running.
