Subject: [PATCH] kni: fix crash with null name

[ upstream commit e716b639856cc4baa46bc6d5bc63bcc1d6bd9cf9 ]

Fix a segmentation fault which occurs when the kni_autotest is run
in the 'test' application.

This segmenation fault occurs when rte_kni_get() is called with a
NULL value for 'name'.

Fixes: 0c6bc8ef70ba ("kni: memzone pool for alloc and release")
