[libvirt] [PATCH 1/4] parallels: Fix connecting to parallels driver

[Maxim Nestratov]

After 55ea7be7, failures of parallelsLoadNetworks and parallelsStorageOpen
started to fail establishing a new connection to parallels driver.
Before this patch we simply ignored such errors.
This patch restores the ability to connect to parallels driver
even if parallelsLoadNetworks fails to get information about
Parallels Bridged networks. This can happen when it is unconfigured
(which is a common case on developers hosts for instance) or configured
incompletely. In any case it is not a severe error and we can ignore it.
Failures of parallelsStorageOpen occured because we incorrectly treated
path to VM' configuration file as a directory. Now initialization of
parallels VM domains home directory is fixed.
