Vmware Import: Cleanup After Failed Attempts to Set up Storage

[apsmr]

Hi,

we tried to set up an ESXi storage to move a few VMs from vmware to pve.

Setting up the storage failed three times (timeout). When I looked more closely to my PVE host, I discovered that it has three fuse mounts in `/var/run/pve/import/esxi`:

```
/dev/fuse on /run/pve/import/esxi/esx-3/mnt type fuse (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)
/dev/fuse on /run/pve/import/esxi/vmware3/mnt type fuse (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)
/dev/fuse on /run/pve/import/esxi/ESX3/mnt type fuse (rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other)
```

Before trying other things, I would like to clean up.
How do I get properly rid of the partially created ESXi storage mounts?

Thanks,

Markus
