net: rswitch: Initialize RX DMA descriptor .die_dt field to DT_FEMPTY
Empty RX DMA descriptor must contain .die_dt field set to DT_FEMPTY,
because hardware DMA overwrites this field to non-DT_FEMPTY when data
are received, and the .recv callback tests the content of RX descriptor
.die_dt field to determine whether hardware did receive any data and
updated the .die_dt field, and based on that information, receives a
packet or not. Fix the incorrect RX DMA descriptor initialization to
assure the .recv callback always works correctly.
