systemc: set Gem5ToTlmBridge blockingRrequest with TLM_UPDATE returning
In Gem5ToTlmBridge::pec, the function expects blockingRequest should be
set no matter the tlm peer returns TLM_UPDATE or TLM_ACCEPTED.
However, current implementation only sets blockingRequest when the tlm
peer returns TLM_ACCEPTED. We should also set blockingRequest when the
tlm peer returns TLM_UPDATE.
