	Variable to temporarily store value of snoopfilter entry in case finishRequest needs to undo changes made in lookupRequest (because of crossbar retry)

Detailed Description

A request lookup must be followed by a call to finishRequest to inform the operation's success.

If a retry is needed, however, all changes made to the snoop filter while performing the lookup must be undone. This structure keeps track of the state previous to such changes.
