media: venus: core: Fix a potential NULL pointer dereference in an error handling path
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'
Fixes: 9e8efdb57879 ("media: venus: core: vote for video-mem path")
