lv_manip: do not check extents for any virtual target

Allow creation of any virtual segment type with just --virtualsize
specified without any real extent size give.

TODO: likely --type error,zero might be later enhanced to use -V
(along with -L) - but since those targets do not allocate real
space, supporting -V makes sense with them.
