f2fs: remove redundant block plug
For buffered IO, we don't need to use block plug to cache bio,
for direct IO, generic f2fs_direct_IO has already added block
plug, so let's remove redundant one in .write_iter.
As Yunlei described in his patch:
-f2fs_file_write_iter
-blk_start_plug
-__generic_file_write_iter
...
-do_blockdev_direct_IO
-blk_start_plug
...
-blk_finish_plug
...
-blk_finish_plug
which may conduct performance decrease in our platform
