Two straightforward fixes. One is a concurrency issue only affecting
SAS connected SATA drives, but which could hang the storage subsystem
if it triggers (because the outstanding command count on error never
goes back to zero) and the other is a NO_TAG fallout from the switch
to hostwide tags which causes the system to crash on module insertion
(we've checked carefully and only the 53c700 family of drivers is
vulnerable to this issue).
