ceph: fix cap_snap and realm split
The cap_snap creation/queueing relies on both the current i_head_snapc
_and_ the i_snap_realm pointers being correct, so that the new cap_snap
can properly reference the old context and the new i_head_snapc can be
updated to reference the new snaprealm's context. To fix this, we:
- move inodes completely to the new (split) realm so that i_snap_realm
is correct, and
- generate the new snapc's _before_ queueing the cap_snaps in
ceph_update_snap_trace().
