Subject: common/dpaax: fix nodes check
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c390b49d74cff8e4efb12b338c9e91421937332f;p=dpdk.git

common/dpaax: fix nodes check

In case the memory for nodes cannot be allocated, there is no need
to check for the length. Also, `node_count` is an unsigned value
and cannot be less than 0.

Coverity issue: 323521
Fixes: 2f3d633aa593 ("common/dpaax: add library for PA/VA translation table")
