Issue: There is possibility of few DCMDs timing out with 'reset_mutex' lock held. As part of DCMD timeout handling, driver calls function megasas_reset_fusion which also tries to acquire same lock 'reset_mutex' and end up with deadlock. Fix: Upon timeout of DCMDs (which are fired with 'reset_mutex' lock held), driver will release 'reset_mutex' before calling OCR function and will acquire lock again after OCR function returns.
