Ack: [Vivid][SRU][PATCH] iwlwifi: mvm: fix BT coex shared antenna activity check

[Jason DeRose]

FYI, I've been testing this fix on a 7260 for the past few hours and haven't encountered any problems.

Tested both 2.4GHz N and AC. The 7260 wasn't effected by the bug (or at least not effected so severely as to make WiFi unusable), but I wanted to make sure there were no regressions.

Simple, clean cherry pick, and confirmed to fix the problem.
