[pbs-devel] [PATCH proxmox-backup] file-restore: strip .img.fidx suffix from drive serials

[Stefan Reiter]

Drive serials have a character limit of 20, longer names like
"drive-virtio0.img.fidx" or "drive-efidisk0.img.fidx" would get cut off.

Fix this by removing the suffix, it is not necessary to uniquely
identify an image.
