As of commit bcc3e1726d ("mmc: block: Use R1 responses for stop cmds for read requests"), stop commands for reads do not have MMC_RSP_BUSY set. In this case we should not wait for a PRG_DONE IRQ after sending the stop command: it will not get raised when the busy flag is not set, causing the request to fail with a timeout.
