[PATCH v2] ath6kl: replace one-element array with flexible-array member

[Atul Raut]

One-element arrays are no longer relevant, and their
place has been taken by flexible array members thus,
use a flexible-array member to replace the one-element
array in struct ath6kl_usb_ctrl_diag_cmd_write

This fixes warnings such as:
./drivers/net/wireless/ath/ath6kl/usb.c:109:8-12: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
