IOCTL read/write tests are carried out using commands 17 (Single BLock Read), 24 (Single Block Write), 18 (Multi Block Read), 25 (Multi Block Write) The tests are carried out on a 64Gb emmc device. All of these tests try to access an "out of range" sector address (0x09B2FFFF). It is seen that without the patch the response received by the user is not OUT_OF_RANGE error (R1 response 31st bit is not set) as per JEDEC specification. After applying the patch proper response is seen. This is because the function returns without copying the response to the user in case of failure. This patch fixes the issue. Hence, this memcpy is required whether we get an error response or not. Therefor it is moved up from the current position up to immediately after we have called mmc_wait_for_req(). The test code and the output of only the CMD17 is included in the commit to limit the message length.
