[PATCH v4 2/2] docs: kernel-parameters: fix a truncated sentence for preempt=lazy

[Quchaosheng]

The preempt=lazy paragraph trails off: "One preemption is when the task
returns to user space." reads as if a preemption and a preemption point
were the same thing, and the sentence does not say what it is describing.

Say which point it means.

Fixes: f66e4a996582 ("sched/core: Update kernel boot parameters for LAZY preempt.")

Changes in v4:
- Drop the Reported-by. There is no report behind it: the wording came out
  of Sebastian's review, so the Suggested-by that v2 had is the tag that
  belongs here, and the Fixes: line v3 dropped belongs here as well.
  No change to the diff.

Changes in v3:
- No change to the diff. The Reviewed-by is for this patch as posted in v2.
