[PATCH] Revert "storageVolCreateXMLFrom: Check if backend knows how to createVol"

[Ján Tomko <jtomko@xxxxxxxxxx>]

This reverts commit 611a278fa46d3136b7fe5c6ab05e660ca3c8fdf4.

According to the original commit message, this is dead code:

  It is highly unlikely that a backend will know how to create a
  volume from a different volume (buildVolFrom) and not know how to
  create an empty volume (createVol).
