Subject: [PATCH 3.13 26/99] iwlwifi: mvm: BT Coex - disable BT when TXing probe request in scan

3.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Emmanuel Grumbach <emmanuel.grumbach@...el.com>

commit 8e2a866ef214af4e104ec8d593e3269d8fe66d19 upstream.

Not doing so will let BT kill our probe requests leading to
failures in scan.
