Fix bug in mb_alloc that made systems configured with
PAGE_SIZE / MCLBYTES == 1 crash. Fix them by changing the
appropriate "allocate new page and bucket" code in mb_alloc to use
the macro for properly grabbing an allocated object from a bucket,
the one that checks whether the bucket is empty.
This should allow ken to continue testing zero-copy stuff on -CURRENT.
Noticed and provided debug info: ken
