AFAICT atari_scsi on aranym never did anything useful. Those aranym users
who need to run Linux 4.5 can set CONFIG_ATARI_SCSI=n or blacklist the
atari_scsi module (up until aranym can be patched).

testing the exception handling fixes for the driver.

Fixing the emulator is the only sensible approach. If S operating systems
have to carry workarounds for B emulator bugs, the cost is (at least)
proportional to S * B.
