transhuge.rst claims seven policies for transparent_hugepage_shmem= and four for transparent_hugepage_tmpfs=. Both boot parameters are parsed by shmem_parse_huge(), which accepts six: always, within_size, advise, never, deny and force. The "four" applies only to the per-mount huge= option (shmem_param_enums_huge). Fix both counts to six.
