f2fs: introduce discard_map for f2fs_trim_fs
This patch adds a bitmap for discard issues from f2fs_trim_fs. There-in rule is to issue discard commands only for invalidated blocks after mount. Once mount is done, f2fs_trim_fs trims out whole invalid area. After ehn, it will not issue and discrads redundantly. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
