mem-cache: Refactor the cache recvTimingReq function

The recvTimingReq function in the cache handles timing requests. Over
time, recvTimingReq has grown in complexity and code size. This change
factors out some of its functionality in two separate functions. The
new functions handle timing requests that hit and timing requests that
miss separately.
