Yun Zhou 416e3a0e42 proc: fix documentation and description of pagemap 
commit dd21bfa425 upstream.

Since bit 57 was exported for uffd-wp write-protected (commit
fb8e37f35a2f: "mm/pagemap: export uffd-wp protection information"),
fixing it can reduce some unnecessary confusion.

Link: https://lkml.kernel.org/r/20220301044538.3042713-1-yun.zhou@windriver.com
Fixes: fb8e37f35a ("mm/pagemap: export uffd-wp protection information")
