ide: fix registers loading order for WIN_SMART in execute_drive_cmd() 

Fix registers loading order for REQ_TYPE_ATA_CMD request with WIN_SMART
command in execute_drive_cmd() (load IDE_FEATURE_REG and IDE_SECTOR_REG
before loading IDE_LCYL_REG and IDE_HCYL_REG).

It shouldn't affect anything (just a usual paranoia to separate changes
which change the way in which hardware is accessed from code cleanups).
