exercise euca.sh should check the volume just created

[Kui Shi]

In devstack, the exercises/euca.sh test the "VOLUME". it should alway check the volume that is just created. Because there may be volumes left by the last failed euca.sh.

    exercise euca.sh check the volume just created

    In devstack, the exercises/euca.sh test the "VOLUME". it should always
    check the volume which was just created. Because there may be volumes
    left by the last failed euca.sh, then the variable VOLUME
    VOLUME=`euca-describe-volumes | cut -f2`
    will be assigned a list of volumes, which is not expected.

    Fixes bug #1191424
