net/enic: avoid error message when no advanced filtering

Browse Source 
Probing the availability of Flow Manager API may print the following
error log.

PMD: rte_enic_pmd: Devcmd 88 failed with error code -1

The error indicates a flow manager operation failed and happens when
advanced filtering is disabled on vNIC. It is harmless but confusing
to the user. Since advanced filtering is a prerequisite, check first
if it is available and avoid the error message altogether.
