cifs: flush data on any setattr
We already flush all the dirty pages for an inode before doing ATTR_SIZE and ATTR_MTIME changes. There's another problem though -- if we change the mode so that the file becomes read-only then we may not be able to write data to it after a reconnect. Fix this by just going back to flushing all the dirty data on any setattr call. There are probably some cases that can be optimized out, but I'm not sure they're worthwhile and we need to consider them more carefully to make sure that we don't cause regressions if we have to reconnect before writeback occurs.
