[ Upstream commit 0e8d040bfa4c476d7d2a23119527c744c7de13cd ]
Otherwise, last .atomic_write_task will be remained in structure
f2fs_inode_info, resulting in aborting atomic_write accidentally
in race case. Meanwhile, clear original_i_size as well.
Fixes: 7a10f0177e11 ("f2fs: don't give partially written atomic data from process crash")
