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.

info that we need to set very urgently.
