sched/wait: Add swq_has_sleeper()

Which is the equivalent of what we have in regular waitqueues.
I'm not crazy about the name, but this also helps us get both
apis closer -- which iirc comes originally from the -net folks.

We also duplicate the comments for the lockless swait_active(),
from wait.h. Future users will make use of this interface.
