iwlwifi: mvm: remove division by size of sizeof(struct ieee80211_wmm_rule)
The subtraction of two struct ieee80211_wmm_rule pointers leaves a result
that is automatically scaled down by the size of the size of pointed-to
type, hence the division by sizeof(struct ieee80211_wmm_rule) is
bogus and should be removed.
Detected by CoverityScan, CID#1467777 ("Extra sizeof expression")
Fixes: 77e30e10ee28 ("iwlwifi: mvm: query regdb for wmm rule if needed")
