gpu: pvr: no need to check for retry failures in PVRSRVMISR
ProcessQueues can't fail any more with a 'retry' error, so checking for
this is not needed. Previously ProcessQueues could fail if sQProcessResource
is locked by someone else. Since sQProcessResource is removed by a previous
change in this patchset that race condition can't happen.
