net: ethernet: stmmac: GMAC4.xx: Fix TX descriptor preparation
On GMAC4.xx each descriptor contains 2 buffers of 16KB (each). Initially, those 2 buffers was filled in dwmac4_rd_prepare_tx_desc but it is actually not needed. Indeed, stmmac driver supports frame up to 9000 bytes (jumbo). So only one buffer is needed.
