mac80211: fix the increment of mesh precedence value
The mesh precedence value in ieee80211_channel_switch should be incremented or set to 1 only if this is the initiator of mesh channel switch. For non-initiator, the precedence value has updated using the Mesh Channel Switch Parameters element. Fix this.
