[PATCH v3 4/4] mm/slub: correct the default value of slub_min_objects in doc

[sxwjean]

From: Xiongwei Song <xiongwei.song@xxxxxxxxxxxxx>

There is no a value assigned to slub_min_objects by default, it always
is 0 that is initialized by compiler if no assigned value by command line.
min_objects is calculated based on processor numbers in calculate_order().
For more details, see commit 9b2cd506e5f2 ("slub: Calculate min_objects
based on number of processors.")
