[ Upstream commit c705a6b3aa7804d7bc6660183f51e510c61dc807 ]
We accidentally return success when adm8211_alloc_rings() fails but we
should preserve the error code.
Fixes: cc0b88cf5ecf ("[PATCH] Add adm8211 802.11b wireless driver")

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.
