mesh: Use correct rate in HT and legacy mixed environment

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

Previously, the mesh STA A sent frame with HT rate even though its HT
was disabled. This commit fixes the issue by checking the local BSS HT
configuration.
