[media] au0828: Refactoring for start_urb_transfer()
This issue was detected by using the Coccinelle software.
1. Let us return directly if a buffer allocation failed.
2. Delete the jump label "err" then.
3. Drop the explicit initialisation for the variable "ret"
at the beginning.
4. Return zero as a constant at the end.
