Function get_pfnblock_flags_mask just calls inline inner __get_pfnblock_flags_mask without any extra work. Just opencode __get_pfnblock_flags_mask in get_pfnblock_flags_mask and replace call to __get_pfnblock_flags_mask with call to get_pfnblock_flags_mask to remove unnecessary __get_pfnblock_flags_mask.
