Meatloaf crashes with `LOAD"$",8` to a real 1541

[fredsa]

To reproduce:

1. Build & flash Meatloaf at HEAD (9becc5f72f4e459274c1932646823aa43478a731)
2. Attach a real 1541 (device 8) and Meatloaf to the C64
3. On meatloaf disable 8Meatloaf
4. LOAD"$",8 from the real 1541

Expected:

• Meatloaf ignores C64<->1541 traffic on device 8

Actual:

• Meatloaf crashes
