Currently the code BUG()'s, if host->mrq is set at the beginning of
msdc_ops_request. This shoould normally not happen, but it is not that
critical, because the critical sections are protected by a spin lock
and in the worst case, some commands to the card are lost, so it is
sufficient to just WARN_ON().
