iwlwifi: mvm: fix first_antenna first_antenna is supposed to return the first antenna as a 0-based bitmap: ANT_A is BIT(0), ANT_B is BIT(1), etc... Since ffs is 1 based (ffs(BIT(0)) = 1), then we had an off-by-one bug: BIT(ffs(ANT_A)) = BIT(ffs(BIT(0))) = BIT(1) = ANT_B. So what we really want is: BIT(ffs(ANT_A) - 1) = BIT(ffs(BIT(0)) - 1) = BIT(0) = ANT_A.
