lvconvert: allow converting type raid1 to type linear

The code could perform this conversion but ironically
did not recognize the standard command form, only the
the unpreferred "implication-based" command form.

"lvconvert --type linear VG/RaidLV" would fail, but
"lvconvert --mirrors 0 VG/RaidLV" would succeed.
