DPDK deployment fails when there is no deprecated parameters

When no deprecated parameters in role_data and enabling flag
'uses_deprecated_params', deployment fails as the parameter_groups
has no parameters added to computeovsdpdk-role file. As there are
no deprecated parameters for this role, this flag should be disabled.
