Warner Losh 4b1ac5c2d8 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.
