wifi: mac80211: reset FILS discovery and unsol probe resp intervals

When ieee80211_stop_ap() deletes the FILS discovery and unsolicited
broadcast probe response templates, the associated interval values
are not reset. This can lead to drivers subsequently operating with
the non-zero values, leading to unexpected behavior.

Trigger repeated retrieval attempts of the FILS discovery template in
ath12k, resulting in excessive log messages such as:

mac vdev 0 failed to retrieve FILS discovery template
mac vdev 4 failed to retrieve FILS discovery template

Fix this by resetting the intervals in ieee80211_stop_ap() to ensure
proper cleanup of FILS discovery and unsolicited broadcast probe
response templates.
