[PATCH v2 2/2] mesh: Use correct rate in 11ac and 11n mixed environment

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

Previously, the mesh STA A sent frame with 11ac rate even though its VHT
was disabled. This patch fixes the issue.
