net/designware: add explicit reset of {tx|rx}_currdescnum
Driver "init" function might be called multiple times. On every "init" Tx/Rx buffer descriptors are initialized: "descs_init" -> "{tx|rx}_descs_init". In its turn those init functions set MAC's "{tx|rx}desclistaddr" to point on the first buffer descriptor in the list. So CPU to start operation from the first buffer descriptor as well after every "init" we have to reset "{tx|rx}_currdescnum".
