Subject: [PATCH] Ruby: Ensure snoop requests are sent using sendTimingSnoopReq

This patch fixes a bug that caused snoop requests to be placed in a
packet queue. Instead, the packet is now sent immediately using
sendTimingSnoopReq, thus bypassing the packet queue and any normal
responses waiting to be sent.
