Fix #129589: Crash when pushing down NLA track

Browse Source 
The issue is that the action line may be there, but containing no action,
`bAnimListElem->data` pointer is a nullptr.

caused by b952782a44
In this refactor the function call was changed from
`BKE_action_frame_range_get` which could handle
the case of a nullptr passed to it.
