sysctl: drop sysctl_is_perm_empty_ctl_table
It is used only twice and those callers are simpler with sysctl_is_perm_empty_ctl_header(). So use this sibling function. This is part of an effort to constify definition of struct ctl_table. For this effort the mutable member 'type' is moved from struct ctl_table to struct ctl_table_header. Unifying the macros sysctl_is_perm_empty_ctl_* makes this easier.
