wifi: mac80211: simplify return value handling of cfg80211_get_radio_idx_by_chan()

Browse source

In several instances where cfg80211_get_radio_idx_by_chan() is called,
redundant checks are performed across function — such as verifying if
wiphy->n_radio < 2 or if the returned index is negative. These checks are
unnecessary, as the return value can be directly compared. Moreover, the
function can be safely called even when radio-level properties are not
explicitly advertised since in such case in each call it is going to get
same error value.

Therefore, simplify the usage of this function across all such cases by
removing redundant conditions and relying on the return value directly.
