libqos/ahci: fix memory management bugs

There's a handful of trivial bugs in the libqos/ahci functions,
squish them together.

- Zero cached pointers after freeing them
- The Command List Buffer is an array of 32x 32 byte structures, not
  32x 8 byte pointers -- it's 1MiB, not 256 bytes. Zero it ALL.
- Free the correct command in ahci_pick_cmd.
