when an empty path is given to the --with-dpdk option
(--with-dpdk="" or --width-dpdk=$NON_SET_ENV_VARIABLE) the configure
script does not show any error and configures OvS without DPDK support,
this can create some confusion.
This patch modifies that behavior showing an explicity error in that case.
