[PATCH v3 10/14] megaraid_sas: Return pended IOCTLs with cmd_status MFI_STAT_WRONG_STATE in case adapter is dead

[Shivasharan S]

Fix - 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.
