Jes, I would like to take this directly to fix the compiler warning. Also I'll
change the commit log to:

rtl8xxxu: tx rate reported before set

Move the dev_info call that attempts to show the rate used before it is set.
Fixes a compiler warning:

drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c: In function 'rtl8xxxu_fill_txdesc_v2':
include/linux/device.h:1214:36: warning: 'rate' may be used uninitialized in this function [-Wmaybe-uninitialized]
#define dev_info(dev, fmt, arg...) _dev_info(dev, fmt, ##arg)

Fixes: b4c3d9cfb607 ("rtl8xxxu: Pass tx_info to fill_txdesc in order to have access to retry count")
