[2/2] media: venus: hfi: avoid null dereference in deinit
Commit Message
If venus_probe fails at pm_runtime_put_sync the error handling first
calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets
core->ops to NULL, hfi_core_deinit cannot call the core_deinit function
anymore.
Avoid this null pointer derefence by skipping the call when necessary.
