fs/buffer.c: clean up EXPORT* macros
According to Documentation/CodingStyle the EXPORT* macro should follow
immediately after the closing function brace line.
Also, mark_buffer_async_write_endio() and do_thaw_all() are not used
elsewhere so they should be marked as static.
In addition, file_fsync() is actually in fs/sync.c so move the EXPORT* to
that file.
