issue: Set MLX5_SHUT_UP_BF if VMA_BF=0

[pasis]

Description

MLX5_SHUT_UP_BF forces rdma-core to create a single NC UAR instead of 16 BF registers. Since VMA_BF=0 is supposed to disable BlueFlame functionality, disable it in rdma-core as well.

What

Set MLX5_SHUT_UP_BF if VMA_BF=0

Why ?

Use NC UAR with disabled BlueFlame.
