[PATCH] mesh: Use correct rate in 11n and legacy mixed environment

[Masashi Honma]

Let mesh STA A is a STA which has config disable_ht=1.
Let mesh STA B is a STA which has config disable_ht=0.
The mesh STA A and B was connected.

Previouly, the mesh STA A sent frame with 11n rate even though its HT
was disabled. This patch fixes the issue.
