[pve-devel] [PATCH qemu-server 2/2] migration: add missing eval on nbdstop with tunnel v2.

[Alexandre Derumier <aderumier@odiso.com>]

It was already done in tunnel v1.

Avoid to avoid migration (and keep both source/targetvm locked) if nbdstop error occur

2023-09-28 16:20:39 ERROR: error - tunnel command '{"cmd":"nbdstop"}' failed - failed to handle 'nbdstop' command - VM 140 qmp command 'nbd-server-stop' failed - got timeout
2023-09-28 16:20:39 ERROR: migration finished with problems (duration 00:01:42)
