Subject: mac80211: don't try to sleep in rate_control_rate_init()
From: Johannes Berg <johannes.berg@intel.com>
[ Upstream commit 115865fa0826ed18ca04717cf72d0fe874c0fe7f ]
In my previous patch, I missed that rate_control_rate_init() is
called from some places that cannot sleep, so it cannot call
ieee80211_recalc_min_chandef(). Remove that call for now to fix
the context bug, we'll have to find a different way to fix the
minimum channel width issue.
