bwi: Mark write-only variable as __unused
We read TX_STATUS1 to acknowledge a TX interrupt. We don't use this value for anything, so mark it as unused. We may be able to eliminate this read, but since this hardware is poorly documented and difficult to test, I'm leaving the read in place. Sponsored by: Netflix
