pcnet: Avoid double conversion via PHYSADDR 

rdra and tdra are already kept converted in the pcnet state structure.
Avoid converting derivatives a second time. The same case with the local
variable xmit_cxda: it already contains a converted cxda address. This
issue only causes troubles when using the pcnet in 16-bit legacy mode.
