Remove the unused local variable refcount for encoder_phys_wb as the one part of wb_enc is used directly.

As I glanced onto this function, it seems you miss updating `ret` here. Could you please fix that too?
Yes, we dont need ret here, its a void function. So we dont need to handle the if (ret) cases as we would never hit them.
I will update this and post v2. I have re-tested this too.
