[pve-devel] [PATCH storage] cifs: fix check connection call

[Fiona Ebner <f.ebner@proxmox.com>]

by not having -W eat the next argument when $scfg->{domain} is defined
but empty.

As reported in the community forum [0], this could lead to issues
adding a storage in the UI.

Didn't have time to look at why it's not an issue in Proxmox VE 7 yet.
