[pve-devel] [PATCH qemu-server v2 1/3] Remove vm_destroy

This function has been used in one place only into which we inlined its
functionality. Removing it avoids confusion between vm_destroy and vm_destroy.
The whole $importfn is executed in a lock_config_full.
As a consequence, for the inlined code:
1. lock_config is redundant
2. it is not possible that the VM has been started (check_running) in the
meanwhile
Additionally, it is not possible that the "lock" property has been written into
the VM's config file (check_lock) in the meanwhile
Add warning after eval so that it does not go unnoticed if it ever comes into
action.

v1->v2:
- Adapt commit message
- Keep $skiplock for readability
- Squash 3/7 "Remove redundant locks" into here
- Squash 5/7 "Remove useless eval" into here:
Actually the eval is not removed anymore but I added a warning instead
