Corrected check for successful LVM sector load [v1.1.1-testing]

The 'DriveIO_LoadLVMSector' function now uses disk i/o semantics,
meaning CY indicates failure and NC indicates success.

CAUTION:
This is a testbuild !
AirBoot uses the BIOS to access disks and a small coding error can trash
partition tables or other vital disk structures. You are advised to make
backups of TRACK0 and EBRs before using this testbuild. More info at:
