cw1200: Add 2byte hole in TXreq for unaligned buf
Adds a 2 bytes hole in the WSM Transmit request when skb->data is
aligned at 2 bytes.This will make the transmit request 4byte aligned.
This optmisation is need for DMA.
The firmware is informed about the hole by setting BIT7 in the
WSM Transmit Request flags.
