net: mvneta: Fix transmit errors due to dirty txdesc
Marvell Neta's transmit descriptor (txdesc) is allocated by dma_alloc_coherent()
but not zeroed before calling mvneta_send the first time. This can cause spurious
transmit errors due to improperly set bits in txdesc's cmd_sts field.
Fix initial transmit errors by always writing whole cmd_sts field instead of ORing
the bits.
