mem: Add check for express snoop in packet destructor
Snoop packets share the request pointer with the originating packets. We need to ensure that the snoop packet destruction does not delete the request. Snoops are used for reads, invalidations, HardPFReqs, Writebacks and CleansEvicts. Reads, invalidations, and HardPFReqs need a response so their snoops do not delete the request. For Writebacks and CleanEvicts we need to check explicitly for whethere the current packet is an express snoop, in whcih case do not delete the request.
