wifi: ath9k: use proper statements in conditionals
A previous cleanup patch accidentally broke some conditional
expressions by replacing the safe "do {} while (0)" constructs
with empty macros. gcc points this out when extra warnings
are enabled:
drivers/net/wireless/ath/ath9k/hif_usb.c: In function 'ath9k_skb_queue_complete':
drivers/net/wireless/ath/ath9k/hif_usb.c:251:57: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body]
251 | TX_STAT_INC(hif_dev, skb_failed);
Make both sets of macros proper expressions again.
Fixes: d7fc76039b74 ("ath9k: htc: clean up statistics macros")
