Subject: net/mlx5: limit the function in local scope
Patch-mainline: v5.6-rc1
Git-commit: 8007880a2ca97c34e7ccd1fcf12daf854b792544
References: jsc#SLE-8464

The function mlx5_buf_alloc_node is only used by the function in the
local scope. So it is appropriate to limit this function in the local
scope.
