wifi: rtw88: Fix inadvertent sharing of struct ieee80211_supported_band data

Browse source

Internally wiphy writes to individual channels in this structure,
so we must not share one static definition of channel list between
multiple device instances, because that causes hard to debug
breakage.

For example, with two rtw88 driven devices in the system, channel
information may get incoherent, preventing channel use.

Copied from commit 0ae36391c8 ("wifi: rtw89: Fix inadverent sharing
of struct ieee80211_supported_band data").
