net: enetc: bring "bool extended" to top-level in enetc_open()

Extended RX buffer descriptors are necessary if they carry RX
timestamps, which will be true when PTP timestamping is enabled.

Right now, the rx_ring->ext_en is set from the function that allocates
ring resources (enetc_alloc_rx_resources() -> enetc_alloc_rxbdr()), and
also used later, in enetc_setup_rxbdr(). It is also used in the
enetc_rxbd() and enetc_rxbd_next() fast path helpers.

We want to decouple resource allocation from BD ring setup, but both
procedures depend on BD size (extended or not). Move the "extended"
boolean to enetc_open() and pass it both to the RX allocation procedure
as well as to the RX ring setup procedure. The latter will set
rx_ring->ext_en from now on.
