[dpdk-stable] [PATCH 19.11 v1 1/1] net/hinic: fix filters on memory allocation failure

[Xiaoyun wang]

[ upstream commit 0c87a15f5f1ccb9eefb6231aea9d095686f2def4 ]

If rte_zmalloc failed, pmd driver should also delete the ntuple
filter or ethertype filter or normal and tcam filter that already
added before.

Fixes: d7964ce192e7 ("net/hinic: check memory allocations in flow creation")
