[libvirt] [PATCH] virSecuritySELinuxTransactionCommit: Return -1 if no transaction is set

[Marc Hartmayer]

Return -1 and report an error message if no transaction is set and
virSecuritySELinuxTransactionCommit is called.

The function description of virSecuritySELinuxTransactionCommit says:

  "Also it is considered as error if there's no transaction set and this
   function is called."
