Stas Sergeev 8187fd8153 disk: fix sectors count truncation for CHS [fixes #10] 
LBA_to_CHS() uses geometry taken from BIOS, but LBA_Transfer()
was using the geometry from VBR. This caused "count" variable
to underflow over unsigned long, then corrupting the entire
DOS memory with the large read.

This patch makes LBA_to_CHS() to return the geometry to caller,
so that the calculus do always match.

Thanks to @ecm-pushbx and @andrewbird for helping to
nail this down.
