Secondary process may not have all the tailq available for
mapping, so better to ignore the error.

e.g. if the primary process is linked with N libs
and secondary process is linked with less number of libs.

dpdk-procinfo results into following error:
EAL: Cannot initialize tailq: VMBUS_RESOURCE_LIST
