Accepting an Allocation Length parameter allows us to test for
truncation of response data, as per SPC5r17 4.2.5.6:
The device server shall terminate transfers to the Data-In Buffer when
the number of bytes or blocks specified by the ALLOCATION LENGTH field
have been transferred or when all available data have been
transferred, whichever is less.
With this change, all existing prin_read_keys() callers continue to use
same ALLOCATION LENGTH value as earlier (16K).

The helper function -2 return paths already print this message, so the
duplicate in the caller can be dropped.

Check that the Persistent Reserve Out PREEMT request removes the
