4.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Shivasharan S <shivasharan.srikanteshwara@xxxxxxxxxxxx> 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.
