[PATCH v2 2/2] docs: kernel-parameters: fix a truncated sentence for preempt=lazy

[Quchaosheng]

The "lazy" entry ends with:

  One preemption is when the task returns to user space.

which is not a sentence.  It is a leftover from shortening "One such
preemption is when the task returns to user space."

Writing it as "preemption point" reads better than restoring the missing
word, so use that.

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

Changes in v2:
- Use "preemption point", Sebastian's wording, instead of restoring the
  missing word.
