 incorrect length calculation"

Hi Greg / stable maintainer(s),

IIUC, this commit is a good candidate for -stable. I just hit the bug on
4.14, because of new vendor firmware that noticed the mismatched length
(an internal "assert"), but it seems like this is equally problematic
from the kernel side for as long as this code existed [1]:

    ath10k: fix scan crash due to incorrect length calculation

Thanks,
Brian

[1] I guess that would be:

Fixes: ca996ec56608 ("ath10k: implement wmi-tlv backend")

which was in v4.0.
