Log Message:
Pull up following revision(s) (requested by kardel in ticket #1217):
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-(
