Don't bother allocating mb_map on these systems. Mbuf clusters are
allocated from a pool, and the MIPS and Alpha use KSEG to map pool pages. So, mb_map wasn't actually being used. Saves around 4MB of kernel virtual address space in a typical configuration. Garbage-collect the related VM_MBUF_SIZE constant.
