[memdisk] Add disk probing code to support a drive shifting limit
Our INT 13h hook will now only shift BIOS drive numbers up to a limit.
This limit is found by probing for a contiguous range of BIOS drives. Anything
above this range of contiguous drive numbers is not shifted, and will thus be
available to callers at the same drive number.
