arch, arm: Return s1Req upon fault in s2Lookup
When a s2Lookup object is created, a new request is created, based
upon the original, stage 1 request sent out by the CPU. When a fault
occurs during the second stage of translation, this new request is
returned. This can lead to issues with the O3 CPU. The O3 fetch stage
will not acknowledge the fault as it is a different request than the
one it sent out and does not contain a contextID. This commit
rectifies this.
