Avoid rereading the superblock in bfree
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.
