wifi: ath9k: use proper statements in conditionals 

[ Upstream commit b7dc753fe3 ]

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.
