[pve-devel] [PATCH v2 container] fix #4846: Avoid the outdated noacl mount option on ext4

[Filip Schauer <f.schauer@proxmox.com>]

Do not use the 'noacl' mount option when mounting a container disk with
an ext4 file system. The option was removed from the kernel in commit
2d544ec923db

The ext4 detection is based on $do_format in alloc_disk.
