[SSSD] [PATCH] SYSDB: Fixing DB update

[Petr Cech]

Hi,

there is patch for #3023 attached.

Reason for this patch is explained in commit message.

I am open to discussion. In my opinion we don't need to connect sysdb 
pointer with domain structure because it is not used in other upgrade 
functions too.

Regards
