Subject: [PATCH -next] sched: Remove unsued extern declarations

commit f64f61145a38 ("sched: remove sched_exit()") removed sched_exit(),
commit ad46c2c4ebce ("sched: clean up fastcall uses of sched_fork()/sched_exit()")
mistakenly change sched_exit() to sched_dead() extern declarations.

And since commit 7c9414385ebf ("sched: Remove USER_SCHED")
uids_sysfs_init() is not used anymore.
