[pve-devel] [PATCH pve-common v2] cli: fix #6762: only copy properties if defined

[Nicolas Frey]

Adds a defined check to the copy, as to not result in the following
error: 

~# pveceph status Can't use an undefined value as a HASH reference at
     /usr/share/perl5/PVE/CLIHandler.pm line 455, <DATA> line 960.

Pressing double tab after status produces the above message.
