        sys/dev/pci/mpii.c: revision 1.22

PR/54045

fix mpii to adhere to physio diagnostic invariant that
fully processed data must not post an error:

1) verify expected scspi state via KASSERT() instead of just
    setting the variables.
2) set xs->resid only in known good conditions
3) insure setting errors in all error paths and refrain
    from clearing xs->resid in error paths.

While there do some cosmectic clean up:
1) extend and relocate some debug output
2) mpii HBAs can also manage non-disk devices like tapes etc,
    so log that physical "devices" instead of physical "disks" are
    attached or detached.

Tested with NEOSeries FlexStor II and luckily a broken tape drive 8-(
