idr: relocate idr_for_each_entry() and reorganize id[r|a]_get_new()
* Move idr_for_each_entry() definition next to other idr related
definitions.
* Make id[r|a]_get_new() inline wrappers of id[r|a]_get_new_above().
This changes the implementation of idr_get_new() but the new
implementation is trivial. This patch doesn't introduce any
functional change.
