async: Introduce async_schedule_dev_nocall()
commit 7d4b5d7a37bdd63a5a3371b988744b060d5bb86f upstream.
In preparation for subsequent changes, introduce a specialized variant
of async_schedule_dev() that will not invoke the argument function
synchronously when it cannot be scheduled for asynchronous execution.
The new function, async_schedule_dev_nocall(), will be used for fixing
possible deadlocks in the system-wide power management core code.
