    virtlockd: Don't report error if lockspace exists
    
    When the qemu or libxl driver is configured to use lockd and
    file_lockspace_dir is set, virtlockd emits an error when libvirtd
    is retarted
    
    May 25 15:44:31 virt81 virtlockd[7723]: Requested operation is not
    valid: Lockspace for path /data/libvirtd/lockspace already exists
    
    There is really no need to fail when the lockspace already exists,
    paricularly since the user is expected to create the lockspace
    specified in file_lockspace_dir. Failure to do so will prevent
    starting any domains
    
    virsh start test
    error: Failed to start domain 'test'
    error: Unable to open/create resource /data/libvirtd/lockspace/de22c4bf931e7c48b49e8ca64b477d44e78a51543e534df488b05ccd08ec5caa: No such file or directory
    
    Also, virLockManagerLockDaemonSetupLockspace already has logic to ignore
    the error. Since callers are not interested in the error, change
    virtlockd to not report or return an error when the specified lockspace
    already exists.
