    sys/dev/disk/dm: Add dm_alloc_string()
    
    Add dm_alloc_string() which kmallocs char* from M_DM.
    
    It was confusing that targets had to use M_DM for status
    purpose while targets had their own M_DMXXX. Using this
    wrapper function makes target code less error prone when
    allocating a string without an extra comment on usage.
