Add a extra field compress_flag to get/set more compress option from/to
compressed inode.

Daeho, Jaegeuk,

Could you please check whether we could add this new field to struct
f2fs_comp_option? so we can expand to allow user to query/config more
options of compressed inode via new ioctl.

It needs to consider before original patches goes to merge window, let
me know you have other concerns.
