BACKPORT: kasan, sched/headers: Uninline kasan_enable/disable_current()
<linux/kasan.h> is a low level header that is included early
in affected kernel headers. But it includes <linux/sched.h>
which complicates the cleanup of sched.h dependencies.
But kasan.h has almost no need for sched.h: its only use of
scheduler functionality is in two inline functions which are
not used very frequently - so uninline kasan_enable_current()
and kasan_disable_current().
Also add a <linux/sched.h> dependency to a .c file that depended
on kasan.h including it.
This paves the way to remove the <linux/sched.h> include from kasan.h.
