Don't free the stream on error if we've successfully added it to the hash table, since it will be freed by virChrdevHashEntryFree callback. Preserve the error message before calling virStreamFree, since it resets the error. Introduced by 4716138, crashing since 6921892. Reported by Sergey Fionov on libvir-list.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
