More fully implement the state machine.
When a command is finished running, we must transition it from INQUEUE to busy state. We were failing to do that, so we hit a panic when the commands were freed. This only affects mpr, mps already did simmilar things. Now both the polling and interrupt paths properly set BUSY as appropriate.
