this lock is used for sriov_gpu_reset, only get this mutex can run into sriov_gpu_reset. we have couple source triggers gpu_reset for SRIOV: 1) submit timedout and trigger reset voluntarily 2) invalid instruction detected by ENGINE and trigger reset voluntarily 2) hypervisor found world switch hang and trigger flr and notify guest to do reset. all need take care and we need a mutex to protect the consistency of reset routine.
