[PATCH] Allow existing LVs with filesystems to be resized (#490913)

[David Cantrell <dcantrell redhat com>]

If you have an existing disk layout and choose custom partitioning and
want to resize an existing logical volume and filesystem, targetSize was
getting the new size value before an ActionFormatResize() was created
for the device, which resulted in a traceback.
