mac80211: encode listen interval for S1G
S1G allows listen interval up to 2^14 * 10000 beacon
intervals. In order to do this listen interval needs a
scaling factor applied to the lower 14 bits. Calculate
this and properly encode the listen interval for S1G STAs.
See IEEE802.11ah-2016 Table 9-44a for reference.
