feature/gfid-access: Always send setattr down in overloaded setxattr.

Problem: File ownership is not being preserved for root in geo-rep
         mountbroker setup.

Analysis and Cause:
         Entry creations for geo-rep is overloaded in ga_setxattr.
         It happens in two phase, entry creation followed by setattr
         to preserve ownership as in master.

         If uid and gid of file being synced is root, setattr was
         not being sent down. Since, the file creation happens with
         non-root user in mountborker geo-rep setup, if setattr is
         not done explicitly, file ownership is not preserved for root.

Solution:
         Always pass setattr down in overloaded ga_setxattr.
