[PATCH 4.9 068/109] mac80211: dont try to sleep in rate_control_rate_init()

From: Greg Kroah-Hartman

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

[ 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.

Fixes: 96aa2e7cf126 ("mac80211: calculate min channel width correctly")
