raid: fix mirror image naming when converting from mirror to raid1

Browse Source 
$ lvcreate -l1 -m1 --type mirror vg
  Logical volume "lvol0" created.
$ lvconvert --type raid1 vg/lvol0

Before:
$ lvs -a vg
  LV                        VG     Active Attr       LSize   Cpy%Sync Layout     Role
  lvol0                     vg     active rwi-a-r---   4.00m 100.00   raid,raid1 public
  [lvol0_mimage_0_rimage_0] vg     active iwi-aor---   4.00m          linear     private,raid,image
  [lvol0_mimage_1_rimage_1] vg     active iwi-aor---   4.00m          linear     private,raid,image
  [lvol0_rmeta_0]           vg     active ewi-aor---   4.00m          linear     private,raid,metadata
  [lvol0_rmeta_1]           vg     active ewi-aor---   4.00m          linear     private,raid,metadata

Incorrect name: lvol0_mimage_0_rimage_0

With this patch applied:
$ lvs -a vg
  LV               VG   Active Attr       LSize Cpy%Sync Layout     Role
  lvol0            vg   active rwi-a-r--- 4.00m 100.00   raid,raid1 public
  [lvol0_rimage_0] vg   active iwi-aor--- 4.00m          linear     private,raid,image
  [lvol0_rimage_1] vg   active iwi-aor--- 4.00m          linear     private,raid,image
  [lvol0_rmeta_0]  vg   active ewi-aor--- 4.00m          linear     private,raid,metadata
  [lvol0_rmeta_1]  vg   active ewi-aor--- 4.00m          linear     private,raid,metadata

Proper name: lvol0_rimage_0
