[PATCH 1/4] util: Umark virBufferCheckErrorInternal as ATTRIBUTE_RETURN_CHECK

[Martin Kletzander <mkletzan@xxxxxxxxxx>]

The function is useful even without using the return value.  And if
needed, the return value can be obtained by other calls as well.  The
potential for clean-up can be seen in the following patch.
