[PATCH 06/13] Bluetooth: btusb: Fix BD_ADDR byte order in btusb_set_bdaddr_wcn6855()

[Zijun Hu <zijun.hu@oss.qualcomm.com>]

For VSC 0xfc14 to set BD_ADDR, the endianness of the BDA parameter is
opposite to other HCI commands like HCI_Create_Connection, but
btusb_set_bdaddr_wcn6855() sends the address without swapping byte
order, resulting in a wrong BD_ADDR being set.

Fix by swapping the input address before issuing the command.
