make W=1 for x86_64 fails with

drivers/net/wireless/ath/wil6210/txrx.c: In function ‘wil_rx_fini’:
drivers/net/wireless/ath/wil6210/txrx.c:550:7: error: variable ‘rc’ set but not
used [-Werror=unused-but-set-variable]

Fix by dropping the variable.

Thanks for finding it.

I will send series of new patches shortly. This will include changes in
rx chain initialization that, among other, remove fragment you fixed.
Reason is firmware API changes.

Thanks, Vladimir
