Subject: [PATCH 3.14 08/73] iwlwifi: mvm: fix failure path when power_update fails in add_interface

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

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

From: Luciano Coelho <luciano.coelho@...el.com>

commit fd66fc1cafd72ddf27dbec3a5e29e99839d1bc84 upstream.

When iwl_mvm_power_update_mac() is called, we have already added the
mac context, so if this call fails we should remove the mac.

Fixes: commit e5e7aa8e2561 ('iwlwifi: mvm: refactor power code')
