Switch to a static block list. This will make it easier to determine
...
which drive we're talking about. 1 is 0x1000_1000 ... 8 is 0x1000_8000

Fixed to use new scheduler return values

Right now, we return a pointer by usize. This is not good programming in
...
Rust. Instead, the scheduler needs to be modified to return a process
structure's reference. Then, we can extract the fields and then switch.
However, this will require us to have to change how the PROCESS_LIST
works. Since it uses move constructs, we cannot move a process out of it
when we replace the process list.

Changed scheduler to only return the frame and satp register. The mepc
...
is now stored in the trap frame.

Finished setup, rearranged queue creation and testing bits. This makes it so we don't have to free anything if we fail after setting up the queue.
