PNOR code update: clear existing volumes before creating new ones

In testing, a number of issues have occurred in which which we have
attempted to create a read-only volume to mount the squashfs file,
but it's failed because of an existing volume or UBI block of the
same name.

This commit resolves those issues by simply removing any mounts or
volumes of the same name prior to creating and mounting a new
read-only volume during the activation process.

Resolves openbmc/openbmc#2109
