HW flushes after QP in error state is not reliable. This can lead to application hang waiting on a completion for outstanding WRs. Implement a SW mechanism to generate completions for any outstanding WR's after the QP is modified to error. This is accomplished by starting a delayed worker after the QP is modified to error and the HW flush is performed. The worker will generate completions that will be returned to the application when it polls the CQ. This mechanism only applies to Kernel applications.
