[patch 2/2] 9p: change an int to unsigned int

The size of things should be unsigned because negative sizes are
silly.  My concern is the the limit checks don't take negative values
into consideration in p9_client_create()
	if (clnt->msize > clnt->trans_mod->maxsize)
		clnt->msize = clnt->trans_mod->maxsize;
and in p9_tag_alloc()
	int alloc_msize = min(c->msize, max_size);

I don't know if this is exported to user space?  Hopefully it's not
too late to change this.
