[PATCH] sched: mark sysrq_sched_debug_show() static

Only sched.c uses sysrq_sched_debug_show, and sched.c includes sched_debug.c,
so all uses of sysrq_sched_debug_show occur in the same source file.

Eliminates a sparse warning:
warning: symbol 'sysrq_sched_debug_show' was not declared. Should it be static?
