>From the very beginning of the DW GMAC v4.10 IP support the driver has used
an invalid DMA IRQ disable method to switch the DMA IRQs off. Since
commit 021bd5e36970 ("net: stmmac: Let TX and RX interrupts be
independently enabled/disabled") a valid method has been added to the
dwmac4_lib.c module, but the commit author forgot to initialize the
corresponding field of the DW MAC DMA operations descriptor with it. That
mistake hasn't caused any problem so far just because the RIE/TIE fields
match in both 4.x and 4.10 IPs. Anyway fix the inconsistency in order to
at least have a coherent driver code.
