Subject: [PATCH] net: wireless/ath: Fix compile error seen with W=1

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.
