[pve-devel] [PATCH storage] cifs: fix adding storage without username in the GUI

[Stoiko Ivanov <s.ivanov@proxmox.com>]

Currently when trying to add a CIFS storage, without providing a
username and passwort it fails while trying to mount the share, due to
the provided 'username=' parameter (w/o actual username).

I think the issue was introduced in
72385de9e23df9f8e438d74ff783a8075f8d1560
with the extracting of sensitive parameters we (rightly) switched to a
definedness check instead of one for truthyness - but an empty
username/password is defined.
