sched/debug: Don't dump sched debug info in SysRq-W
commit
fb90a6e93c0684ab2629a42462400603aa829b9c upstream.
sysrq_sched_debug_show() can dump a lot of information. Don't print out
all that if we're just trying to get a list of blocked tasks (SysRq-W).
The information is still accessible with SysRq-T.
