- move log into metadata part of disk, so that marking
that the log's blocks are in use falls out for free
- superblock describes the whole disk (sizes and offets)
- sizes and offsets are computed in one place (mkfs) and
the rest of the code refers to the superblock for these values,
instead of recomputing them.

The superblock is read when the first process returns to
userspace (via the call to `iinit` from the first invocation of
`forkret`, when `first` is still set to 1) and cached in a
global; it is treated as immutable from that point on. There is
no reason to re-read it in bfree.
Removing this call seems to have simply been missed in 8320d61b
when this general area was last touched. Remove it now to avoid
potential confusion.
