When vg insufficient lv:lvol0 will crearte by default

[HYSong]

It will create a default LV named lvol0,
when executing 'lvcreate -T -L <lv_size> --poolmetadatasize <pool_metadata_size >'
and the sum of lv_size and pool_metadata_size larger than vg_size.

I think it no use to create a LV named lvol0 when insufficient error occurred.
