The normal path of the function makes the assumption that
'pm_ops->core_power' may be NULL.
We should make the same assumption in the error handling path or a NULL
pointer dereference may occur.
Add the missing test before calling 'pm_ops->core_power'

Hi,
this was sent duing the summer holidays. Since then, a few other patches
have been merged in linux-next for this file.
So, this is a polite reminder.
