Matthias Bolte ee47d23629 esx: Simplify esxPrivate pointer handling in esxOpen 
Commit 4445e16bfa changed the signature
of esxConnectToHost and esxConnectToVCenter by replacing the esxPrivate
pointer with virConnectPtr. The esxPrivate pointer was then retrieved
again from virConnectPtr's privateData. This resulted in a NULL pointer
dereference, because the privateData pointer was not yet initialized at
the point where esxConnectToHost and esxConnectToVCenter are called.

This was fixed in commit b126715a48 that
moved the initialization of privateData before the problematic calls.

Simplify the logic by making the call to esxFreePrivate unconditional and
changing esxConnectToHost and esxConnectToVCenter back to take a esxPrivate
pointer directly. This allows to assign esxPrivate to the virConnectPtr's
privateData pointer as one of the last steps in esxOpen making it more
obvious that it is not initialized during the earlier steps of esxOpen.

         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.
