Subject: [PATCH] net/e1000: fix null pointer check

[ upstream commit 516e525ebfcf9875c86eb5ce88a536470e279739 ]

There are several func calls to rte_zmalloc() which don't have null
pointer check for the return value. It fixes that by adding null
pointer check.

Fixes: 22bb13410cb2 ("net/igb: create consistent filter")
