ath9k_htc: Silence undersized packet warnings

[ Upstream commit 450edd2805 ]

Some devices like TP-Link TL-WN722N produces this kind of messages
frequently.

kernel: ath: phy0: Short RX data len, dropping (dlen: 4)

This warning is useful for developers to recognize that the device
(Wi-Fi dongle or USB hub etc) is noisy but not for general users. So
this patch make this warning to debug message.
