Log Message:
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.
