Description:
Max value of innodb_ft_sort_pll_degree described in Reference Manual(https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_ft_sort_pll_d...) is 32.

In fact，16 is the Max value of innodb_ft_sort_pll_degree in source code:
static MYSQL_SYSVAR_ULONG(ft_sort_pll_degree, fts_sort_pll_degree,
  PLUGIN_VAR_RQCMDARG | PLUGIN_VAR_READONLY,
  "InnoDB Fulltext search parallel sort degree, will round up to nearest power of 2 number", NULL, NULL, 2, 1, 16, 0);

The same issue exists in 5.6,5.7,8.0. 

How to repeat:
no test case needed here

Suggested fix:
Amend the Max value of innodb_ft_sort_pll_degree to 16 in Reference Manual.
