Add a quirk record for the Tandberg 42XX series. Not only that these

Browse Source 
drives require ST_Q_SNS_HLP, they also wrongly accept a blocksize of
1024 in the first place (for a QIC-150 cartridge), but complain later
about it.  The hack is to only probe for 512 for them.

Reorder the entries in st_decide_mode() so that QIC >= 525 is properly
accepted as variable blocksize.
