[PATCH 6.1.y 1/2] Bluetooth: Remove usage of the deprecated ida_simple_xx() API

[Sasha Levin <sashal@kernel.org>]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 9c16d0c8d93e3d2a95c5ed927b061f244db75579 ]

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

Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_max() is inclusive. So a -1 has been added when needed.
