printk_ringbuffer: Avoid needless read of prb_desc
Since commit f244b4dc53e5 ("printk: ringbuffer: Improve prb_next_seq()
performance"), desc_read() allows @desc_out to be NULL. We can drop the
local `desc` variable in desc_reopen_last() and prb_first_seq(). Also
update the comment for desc_read().
v1->v2:
Update the comment suggested by John.
