[PATCH 2/2 net-next] ipvlan: Remove usage of the deprecated ida_simple_xx() API

From: Christophe JAILLET
Date: Fri Jan 05 2024 - 04:35:29 EST


ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().

This is less verbose.

Note that the upper bound of ida_alloc_range() is inclusive while the one
of ida_simple_get() was exclusive. So calls have been updated accordingly.
