mac80211: silence mesh rate mismatch warning (#3416)

Printing a warning everytime a rate mismatch is detected is a bit to
much. With many mesh neighbors, this quickly results in the kernel log
being spammed with these messages.

 Subject: net: mac80211: override incompatible basic-rates for mesh
 
+This is a dirty hack for Gluon.
+
+We assume basic rate setup only affects the rate-controller on the TX
+side. As all devices we support have at least a 802.11n radio and thus
+cover 802.11b as well as 802.11g on 2.4 GHz, they are compatible with
+each other.
+
+As the basic rate was incorrectly set for mesh interfaces in the past,
+connections between mesh neighbors would fail when altering the basic
+rate.
+
+This patch ignores mismatches in the basic-rate field. By doing so, we
+avoid implementing some sort of scheduled switch between wireless
+configurations.
