[PATCH] make console_conditional_schedule() __sched and use cond_resched()

Relatively minor add-on (not necessarily tied to it or required to be taken
or a fix for any bug).  Since cond_resched() is using PREEMPT_ACTIVE now,
it may be useful to update the open-coded instance of cond_resched() to use
the generic call.  Also, it should probably be __sched so the caller shows
up in wchan.
