[pve-devel] [PATCH installer] fix behavior if zfs disks have no by-id path

[Aaron Lauterer]

in some situations it is possible, that a disk does not have a
/dev/disk/by-id path, mainly AFAICT inside VMs with virtio disks.

Commit e1b490865f750e08f6c9c6b7e162e7def9dcc411 forgot to handle this
situation which resultet in a failed installation.

thanks @stoiko for helping me debugging this.

tested with ZFS (3 disks, raidz1) and ext4 in UEFI and BIOS
mode.
