Subject: [PATCH] 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")
