FDC: Fix data transfer len (Hervé Poussineau)
In floppy controller, transfer data len is not correctly calculated. We should read up to the last sector specified by the caller, and not up to the last sector of the floppy. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4294 c046a42c-6fe2-441c-8c8c-71466251a162
