[PATCH 2/7] parallels: fix parallelsLoadNetworks

[Maxim Nestratov <mnestratov@xxxxxxxxxxxxx>]

Don't fail initialization of parallels driver if
parallelsLoadNetwork fails for optional networks.
This can happen when some of them are added manually
and configured incompletely. PCS requires only two networks
created automatically (named Host-Only and Bridged), others
are optional and their incompletenes can be ignored.
