storwize: create_flashcopy_to_consistgrp should call get_vdisk_attributes if the size and pool information is missing

[Chhavi Agarwal]

create_flashcopy_to_consistgrp is called during create_group_snapshot and create_cg_from_source
calling methods has the size and pool information, in such cases we can avoid the get_vdisk_attribute call for create_flashcopy_to_consistgrp.
