Pass the vm_page's address to sf_buf_alloc(); map the vm_page as part
of sf_buf_alloc() instead of expecting sf_buf_alloc()'s caller to map it.

The ultimate reason for this change is to enable two optimizations:
(1) that there never be more than one sf_buf mapping a vm_page at a time
and (2) 64-bit architectures can transparently use their 1-1 virtual
to physical mapping (e.g., "K0SEG") avoiding the overhead of pmap_qenter()
and pmap_qremove().
