qcacld-3.0 : Enable address alignment adjust for TXDMA
Per HW team's analysis, we find a TXDMA HW limitation:
ADDR0&0x1FFFFFFF8 should not equal ADDR1&0x1FFFFFFF8.
Otherwise, TXDMA will run into exception, which cause TX
fail.
ADDR0: the address of last words in previous buffer;
ADDR1: the address of first words in next
buffer;
