kernel: enable InfiniBand/RoCE support in mlx5 kernel config fragment

Browse Source 
Add the kernel configuration options required for RDMA / RoCE operation
with Mellanox ConnectX / BlueField VFs:

  - CONFIG_INFINIBAND: IB subsystem core
  - CONFIG_INFINIBAND_ADDR_TRANS: RoCEv2 GID table management
  - CONFIG_INFINIBAND_USER_ACCESS: userspace verbs (/dev/infiniband/uverbs*)
  - CONFIG_INFINIBAND_USER_MAD: userspace MAD interface
  - CONFIG_MLX5_INFINIBAND: mlx5_ib ConnectX IB/RoCE driver
  - CONFIG_CGROUP_RDMA: RDMA cgroup controller (required by mlx5_ib)

Bump kata_config_version to 196 to trigger a kernel rebuild.
