For some commands it means waiting longer than needed for the timer to expire, which may not a big issue, but still. For other commands, like for an erase (CMD38) that uses a R1B response, may require longer timeouts than 1s. In these cases, we may end up treating the command as it failed, while it just needed some more time to complete successfully. Fix the problem by respecting the cmd->busy_timeout, which is provided by the mmc core.
