systemc: fix the payload and packet association in Gem5ToTlm bridge
If a request is initiated by systemc, passed through TlmToGem5 bridge
and Gem5ToTlm bridge, it wouldn't have the systemc extension about the
association. This feature is also used in TlmToGem5 bridge to detect if
the packet is allocated in the current instance in async interface. In
that case, we would lose the association in the Gem5ToTlm bridge async
interface. For not making wide change, we need an extra way to support
the association in Gem5ToTlm bridge async interface.
This change adds another map to record the association and clears when
the TLM transaction is completed.
