John Ferlan 40e904490f libxl_driver: Resolve Coverity errors
1. The virObjectLock() call was unconditional, but Unlock was conditional
   on vm being valid.  Removed the check

2. A call to virDomainEventNewFromObj() isn't guaranteed to return an
   event - that check needs to be made prior to libxlDomainEventQueue()
   of the event. Did not add libxlDriverLock/Unlock around the call since
   some callers already have lock taken

3. Need to initialize fd = -1 in libxlDoDomainSave() since we can jump
   to cleanup before it's set.

4. Missing break;'s in libxlDomainModifyDeviceFlags() for case
   LIBXL_DEVICE_UPDATE.  The default: case would report an error

         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.

Description
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
