drm/xe: Make xe_ggtt_node_insert return a node

This extra step is easier to handle inside xe_ggtt.c and makes
xe_ggtt_node_allocated a simple null check instead, as the intermediate
state 'allocated but not inserted' is no longer used.

Privatize xe_ggtt_node_fini() and init() as they're no longer used
outside of xe_ggtt.c
