wifi: mac80211: Fix puncturing bitmap handling in __ieee80211_csa_finalize()

'changed' can be OR'ed with BSS_CHANGED_EHT_PUNCTURING which is larger than
an u32.
So, turn 'changed' into an u64 and update ieee80211_set_after_csa_beacon()
accordingly.

In the commit in Fixes, only ieee80211_start_ap() was updated.
