mm: fix <linux/pagemap.h> stray kernel-doc notation

commit 083fb8ed upstream.

Delete stray (second) function description in find_lock_page()
kernel-doc notation.

Note: scripts/kernel-doc just ignores the second function description.

Fixes: 2457aec6 ("mm: non-atomically mark page accessed during page cache allocation where possible")
