[virt-tools-list] [virt-viewer][PATCH] Don't SIGSEGV if no transport is used.

[Michal Privoznik]

One of previous commits (74b1b62510d939) allowed us to connect to
localhost directly if ssh transport was used. However, if there's
not transport, we SIGSEGV'ed as g_str_equal doesn't like NULL as
one of arguments. Change this to g_strcmp0 which does the same
service but is more friendly to NULL arguments.
