[PATCH 10/10] Don't ignore allocation failure in virCommandAddEnvPassCommon

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

The virCommandAddEnvPassCommon method ignored the failure to
pre-allocate the env variable array with VIR_RESIZE_N. While
this is harmless, it confuses the test harness which is trying
to validate OOM handling of every individual allocation call.
