[PATCH] cmd: ubi: don't allow to rename a volume to a name that already exist

This commits add a check on the command ubi rename. This check avoids to rename a volume to with a name that is already used on another ubi volume. If two volumes has the same name, then the ubi device can't be mounted anymore.
