f2fs: fix to clear FI_NO_PREALLOC
We need to clear FI_NO_PREALLOC flag in error path of f2fs_file_write_iter, otherwise we will lose the chance to preallocate blocks in latter write() at one time. Fixes: dc91de78e5e1 ("f2fs: do not preallocate blocks which has wrong buffer") Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
