[dpdk-dev] [PATCH] net/nfp: fix null pointer check

[Alejandro Lucero <alejandro.lucero@netronome.com>]

First, the received pointer was not checked before. Then the pointer
from malloc was not the one used in the existing check.

Fixes: ad60bca34899 ("net/nfp: read PF port MAC addr using NSP")
Coverity: 195027
