Modified Files:
        src/sys/kern: kern_entropy.c

Log Message:
Lock the rndsource list without E->lock for ioctls too.

Use the same mechanism as entropy_request, with a little more
diagnostic information in case anything goes wrong.  No need for
LIST_FOREACH_SAFE; elements cannot be deleted while the list is
locked.

This is part II of avoiding percpu_foreach with spin lock held.
