[pve-devel] [PATCH container] fix #5666: fix quota regression due to device passthrough

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

This commit fixes a regression introduced by
commit ce1976b85361 ("Add device passthrough")

Prior to the addition of device passthrough, the `lxc-pve-autodev-hook`
would invoke `PVE::LXC::Tools::for_current_devices` only once. If the
device list was empty, `exit 0` would be called and the
`lxc-pve-autodev-hook` would exit.

However, with the new device passthrough logic, when no devices were
passed through, the `exit` call would be encountered prematurely.
This would prevent the subsequent iteration over passthrough mounts from
occurring.

This commit resolves the issue by replacing the premature `exit` call
with a `return` statement, ensuring the `lxc-pve-autodev-hook` continues
executing and processes the passthrough mounts as expected.
