    Remove dm_setup(remove) call in volume_delete.

    While it makes sense to perform the dm_setup(remove) before
    performing the lvm remove, it seems to cause some buffer IO
    errors as evident by kern.log.

    I'm also a bit suspicous in that it seems the delete timeouts
    we see seems to have increased in frequency with this addition.
    I propose this step is removed until we completely understand the
    impact of the kernel error on Precise kernels.

    Fixes bug: #1075675
