core, webadmin: Disable sparsify for pre-allocated disks

* Disable 'Sparsify' button in UI for preallocated disks.
* Return error from SparsifyImageCommand, if it was called for
pre-allocated disk.

virt-sparsify works on pre-allocated disks, but its usage is not
justified for this case. User chooses pre-allocated option if she needs
better performance, because no additional allocation and no
fragmentation will occur when the disk is used. Deallocating some
clusters as result of sparsification will overturn this advantage. If
user wants to save space at cost of some performance decrease, she can
select thin-provisioned option.
