[libvirt] [PATCH] storage: revert bogus raw volumes support check

[Roman Bogorodskiy]

Commits bb5f2dc and 6682d62 added a check like:

  if (vol->target.format != VIR_STORAGE_FILE_RAW)

to the CreateVol method for zfs and logical storage backends
respectively. However, this check is bogus because
virStorageVolDefParseXML() in conf/storage_conf.c sets target.format
only if volOptions in virStoragePoolTypeInfo has formatFromString set,
and that's not the case for zfs and logical backends. So the check
always fails and breaks volume creation.

Thus, revert those commits.
