lvcreate: don't put VG name in LV name

[ggzengel]

Wrong usage:

# lvcreate --size 7204k -n VG1/vm-107-disk-2.meta_00000 -y -m 1 /dev/nvme0n1 /dev/nvme1n1
  Inconsistent volume group names given: "VG1" and "nvme0n1"
  Run `lvcreate --help' for more information.

Right usage:

# lvcreate --size 7204k VG1 -n vm-107-disk-2.meta_00000 -y -m 1 /dev/nvme0n1 /dev/nvme1n1
  Rounding up size to full physical extent 8.00 MiB
  Logical volume "vm-107-disk-2.meta_00000" created.

I use this to put the meta data to the Intel Optane as RAID1:
linstor sp sp px1 zfs_12_meta StorDriver/LvcreateOptions "-m 1 /dev/nvme0n1 /dev/nvme1n1"
linstor sp sp px2 zfs_12_meta StorDriver/LvcreateOptions "-m 1 /dev/nvme0n1 /dev/nvme1n1"

I get this:

Description:
    (Node: 'px2') Failed to create lvm volume

    Standard out:

For a work around I use this:

linstor sp sp px1 zfs_12_meta StorDriver/LvcreateOptions "-m 1 VG1 /dev/nvme0n1 /dev/nvme1n1"
SUCCESS:
    Successfully set property key(s): StorDriver/LvcreateOptions
SUCCESS:

You are right. This will be fixed in the next release.
