[PATCH 1/3] uuid: Fix coverity warning of unchecked return value

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Coverity checks for patterns of handling return values of functions.
Some recent addition must have tripped a threshold where coverity now
complains that we usually check the return value of virUUIDGenerate but
don't do it in one place. Add a check to make coverity happy.
