LU-1303 osd: zfs-osd should initialize local objects on MDS

zfs-osd to call llo_local_objects_setup() to initialize local
MDS objects (like ldiskfs-osd does).

zfs-osd should not try to control naming for objects maintained
by MDT/MDT (initialized with llo_local_objects_setup()).

disable LASSERT() in MGS: with zfs backend it's not correct.

MDT does not need to access configs, so disable setup of llogs
in MDT.
