6.6-stable review patch. If anyone has any objections, please let me know.

From: Christophe JAILLET christophe.jaillet@wanadoo.fr
[ Upstream commit 920e7522e3bab5ebc2fb0cc1a034f4470c87fa97 ]
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.
