net/enic: fix name of classifiers hash table

net/enic: fix name of classifiers hash table

The enic_clsf_init() function is called once per enic instance, but it
used a static name to create the hash table.  Consequently when using
more than one enic instance, there was a name collision which caused
errors:

EAL: memzone_reserve_aligned_thread_unsafe():
  memzone<RG_HT_enicpmd_clsf_hash> already exists
RING: Cannot reserve memory
HASH: memory allocation failed
PMD: rte_enic_pmd: Init of hash table for clsf failed.
  Flow director feature will not work

This patch changes the name to be unique per enic instance.

Fixes: fefed3d1e62c ("enic: new driver")
