PM: sleep: Make pm_wakeup_clear() call more clear
Move pm_wakeup_clear() to the same location as other functions that do
bookkeeping prior to suspend_prepare().
Since calling pm_wakeup_clear() is a prerequisite to setting up for
suspend and enabling functionalities of suspend (like aborting during
suspend), moving pm_wakeup_clear() higher up the call stack makes its
intent more clear and obvious that it is called prior to
suspend_prepare().
After this change, there is a slightly larger window when abort events
can be registered, but otherwise suspend functionality is the same.
