[SSSD] [PATCHES] fill_initgr: add original primary GID if available

[Sumit Bose]

Hi,

the attached patches should fix
https://fedorahosted.org/sssd/ticket/2027, i.e. always show that and AD
user is a member of it's primary AD group, even for subdomains.

The first patch in this series just fixes a typo I came across while
working at #2027.

bye,
Sumit
