From: Eyal Shapira <eyal at wizery.com>

commit c93edc639392df733c7d72db4376a9add775d18a upstream.

commit 5c90422439d6
"iwlwifi: mvm: don't allow diversity if BT Coex / TT forbid it"
broke Rx with 2 chains for diversity.
This had an impact on throughput where we're using only a single
stream (11a/b/g APs, single stream APs, static SMPS).
