scsi: megaraid_sas: Return pended IOCTLs with cmd_status MFI_STAT_WRONG_STATE in case adapter is dead
commit eb3fe263a48b0d27b229c213929c4cb3b1b39a0f upstream.
After a kill adapter, since the cmd_status is not set, the IOCTLs will
be hung in driver resulting in application hang. Set cmd_status
MFI_STAT_WRONG_STATE when completing pended IOCTLs.
