After commit 6307f8fee295b364716d28686df6e69c2fee751a
("security: remove dead hook task_setgroups"), set_groups
will always return zero, so we could just remove return
value of set_groups.This patch reduce code size, and simplfy code logician to use set_groups, because we don't need to check its return value anymore.
