Fix erroneous use of device blocksize instead of logical sector size in
Atari GEMDOS FAT code (GEMDOS uses a 16 bit FAT and a constant 2 logical
sectors per cluster, and modifies the logical sector size to cope with the
limits imposed by the 16 bit FAT). The bug was probably introduced by me when
porting this code forward from 2.4.
With this fix, I can successfully mount GEMDOS partitons up to 256 MB in size
as
prepared by Petr Stehlik. 512 MB require 8k sector size, sorry.
