We accidentally print the rate before we know it for txdesc_v2:
wireless/realtek/rtl8xxxu/rtl8xxxu_core.c: In function 'rtl8xxxu_fill_txdesc_v2':
wireless/realtek/rtl8xxxu/rtl8xxxu_core.c:4848:3: error: 'rate' may be used uninitialized in this function [-Werror=maybe-uninitialized]
txdesc_v1 got it right, so let's do it the same way here.
Fixes: b4c3d9cfb607 ("rtl8xxxu: Pass tx_info to fill_txdesc in order to have access to retry count")

Hi Arnd,
Thanks for the patch - Barry Day already posted a patch for this which
Kalle has applied to the wireless tree.
Cheers,
