Subject: f2fs: fix to clear FI_NO_PREALLOC

From: Chao Yu <yuchao0@huawei.com>


[ Upstream commit 28cfafb73853f0494b06649716687a3ea07681d5 ]

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")
