iwlwifi: mvm: support sta_statistics() even on older firmware

BugLink: https://bugs.launchpad.net/bugs/1836968
commit ec484d03ef0df8d34086b95710e355a259cbe1f2 upstream.

The oldest firmware supported by iwlmvm do support getting
the average beacon RSSI. Enable the sta_statistics() call
from mac80211 even on older firmware versions.
