Subject: [PATCH] fuse: Don't do file_update_time for write_operation.

For direct-write and normal-write operations, after write they will call fuse_invalidate_attr.
So it's make no sense to call file_update_time before writing.

In function file_update_time, there is other thing which update version of
inode.For this i am not sure.
