Toomas Soome 1ecc859193 dosfs support in libstand is broken since r298230
Apparently the libstand dosfs optimization is a bit too optimistic
and did introduce possible memory corruption.

This patch is backing out the bad part and since this results in
dosfs reading full blocks now, we can also remove extra offset argument
from dv_strategy callback.

The analysis of the issue and the backout patch is provided by Mikhail Kupchik.
