Lihua Liu 286b038d12 qcacmn: Add workaround for TXDMA HW limitation 
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;

We hit this limitation in NAT forward TSO jumbo case whose buffer
address of two fragments like below:
tso_frags = (
(length = 0x42, vaddr = 0xFFFFFFD0F5FA2F82, paddr = 0x1F5FA2F82),
(length = 0x05A8, vaddr = 0xFFFFFFD0F5FA2FC4, paddr = 0x1F5FA2FC4)
In this case, ADDR0 = 0x1F5FA2F82 + 0x42 -2 = 0x1F5FA2FC2,
ADDR1 = 0x1F5FA2FC4, then
ADDR0&0x1FFFFFFF8 = ADDR1&0x1FFFFFFF8.
To avoid this, shift server bytes for ADDR0.
