hw/sd: ssi-sd: Fix the wrong command index for STOP_TRANSMISSION

Browse Source 
This fixes the wrong command index for STOP_TRANSMISSION, the
required command to interrupt the multiple block read command,
in the old codes. It should be CMD12 (0x4c), not CMD13 (0x4d).

Fixes: 775616c3ae ("Partial SD card SPI mode support")
