[libvirt] [PATCH] virt-admin: Properly fix the default session daemon URI to admin server

[Erik Skultety]

Commit 30ce2f0e tried to fix the issue with an incorrect session URI to admin
server but it messed up the checks:

    if (geteuid == 0 && VIR_STRDUP(*uristr, "libvirtd:///system") < 0)
        return -1;
    else if (VIR_STRDUP(*uristr, "libvirtd:///session") < 0)
        return -1;

So if a client executed with root privileges tries to connect, its euid is
checked (true) and the correct URI is successfully copied to @uristr (false),
therefore the 'else' branch is taken and @uristr is replaced by the session URI
which for root results in:
    Failed to connect socket to '/root/.cache/libvirt/libvirt-admin-sock':
    No such file or directory
