[PATCH mt76-next 17/25] wifi: mt76: mt7915: upload the CSA beacon only once

[Felix Fietkau <nbd@nbd.name>]

At the start of a CSA, __ieee80211_channel_switch() reports
BSS_CHANGED_BEACON with csa_active set and then calls
.channel_switch_beacon. mt7915_bss_info_changed() and
mt7915_channel_switch_beacon() thus both upload the same CSA beacon,
and each upload passes the initial count of the template to the
firmware.

Drop mt7915_channel_switch_beacon(). mac80211 calls it only after a
BSS_CHANGED_BEACON report, so mt7915_bss_info_changed() already uploads
the CSA beacon, like mt7996 does.

Fixes: e57b7901469f ("mt76: add mac80211 driver for MT7915 PCIe-based chipsets")
