net/sfc: fix VF error/missed stats mapping

VADAPTER_RX_OVERFLOW means Rx statistics overflow, not a missed
packet because of overflow.

VADAPTER_RX_BAD_PACKETS accumulates a number of error conditions,
but mainly impossibility to deliver because of no descriptors
available, so it is better to classify it as imissed.
