ide-tape: fix potential fs requests bug
ide-tape had a potential bug for fs requests when preparing the command
packet: it was writing the transfer length as a number of fixed blocks.
However, the block layer implies 512 byte blocks and ide-tape can have
other block sizes so account for that too.
ide-floppy does this calculation properly with the block size factor
(floppy->bs_factor).
