Markus Armbruster 64eaa82095 hw: Replace trivial drive_get_next() by drive_get() 
drive_get_next() is basically a bad idea.  It returns the "next" block
backend of a certain interface type.  "Next" means bus=0,unit=N, where
subsequent calls count N up from zero, per interface type.

This lets you define unit numbers implicitly by execution order.  If the
order changes, or new calls appear "in the middle", unit numbers change.
ABI break.  Hard to spot in review.

A number of machines connect just one backend with drive_get_next().
Change them to use drive_get() directly.  This makes the (zero) unit
number explicit in the code.
