sched: Fix KCSAN noinstr violation
[ Upstream commit e0b081d17a9f4e5c0cbb0e5fbeb1abe3de0f7e4e ]
With KCSAN enabled, end_of_stack() can get out-of-lined. Force it
inline.
Fixes the following warnings:
vmlinux.o: warning: objtool: check_stackleak_irqoff+0x2b: call to end_of_stack() leaves .noinstr.text section
