[PATCH 6.17 362/563] wifi: mt76: mt7996: remove redundant per-phy mac80211 calls during restart

6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Felix Fietkau nbd@nbd.name

[ Upstream commit 0a5df0ec47f7edc04957925a9644101682041d27 ]

There is only one wiphy, so extra calls must be removed. For calls that need to remain per-wiphy, use mt7996_for_each_phy
