Daniel P. Berrange 41ac222e52 Fix error reporting when fetching SCSI/LVM keys 
The current  virStorageFileGet{LVM,SCSI}Key methods return
the key as the return value. Unfortunately it is desirable
for "NULL" to be a valid return value, as well as an error
indicator. Thus the returned key must instead be provided
as an out-parameter.

When we invoke lvs or scsi_id to extract ID for block devices,
we don't want virCommandWait logging errors messages. Thus we
must explicitly check 'status != 0', rather than letting
virCommandWait do it.

         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.
