When attempting to backport gluster pools to an older versoin where there is no VIR_STRDUP, I got a crash from calling strdup(,NULL). Rather than relying on the current else branch safely doing nothing when there is no fd, it is easier to just skip it. While at it, there's no need to explicitly set perms.label to NULL after a VIR_FREE(). * src/storage/storage_backend.c (virStorageBackendUpdateVolTargetInfoFD): Minor optimization.

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.
