csi: explicitly set Topology feature-gate

issue:
external-provisioner (v5) enabled topology feature-gate by default
and the current implementation in Rook uses a conditional block to
enable the topology feature gate. This approach now does not directly
reflect the state of the `CSI_ENABLE_TOPOLOGY`.

fix:
replacing the conditional block with a direct use of the
`CSI_ENABLE_TOPOLOGY` for flag value.
