[PATCH] eal: fix check for default plugin directory

[Bruce Richardson]

The check for the existence of the default plugin directory calls stat
using an incorrect variable, which will cause a NULL pointer dereference
error.

Coverity issue: 198440
Fixes: d6a4399cdfc9 ("eal: avoid error for non-existent default PMD path")
