numa: Parse initiator= attribute before cpus= attribute

numa: Parse initiator= attribute before cpus= attribute

When parsing cpus= attribute of -numa object couple of checks
is performed, such as correct initiator setting (see the if()
statement at the end of for() loop in
machine_set_cpu_numa_node()).

However, with the current code cpus= attribute is parsed before
initiator= attribute and thus the check may fail even though it
is not obvious why. But since parsing the initiator= attribute
does not depend on the cpus= attribute we can swap the order of
the two.

It's fairly easy to reproduce with the following command line
(snippet of an actual cmd line):

  -smp 4,sockets=4,cores=1,threads=1 \
  -object '{"qom-type":"memory-backend-ram","id":"ram-node0","size":2147483648}' \
  -numa node,nodeid=0,cpus=0-1,initiator=0,memdev=ram-node0 \
  -object '{"qom-type":"memory-backend-ram","id":"ram-node1","size":2147483648}' \
  -numa node,nodeid=1,cpus=2-3,initiator=1,memdev=ram-node1 \
  -numa hmat-lb,initiator=0,target=0,hierarchy=memory,data-type=access-latency,latency=5 \
  -numa hmat-lb,initiator=0,target=0,hierarchy=first-level,data-type=access-latency,latency=10 \
  -numa hmat-lb,initiator=1,target=1,hierarchy=memory,data-type=access-latency,latency=5 \
  -numa hmat-lb,initiator=1,target=1,hierarchy=first-level,data-type=access-latency,latency=10 \
  -numa hmat-lb,initiator=0,target=0,hierarchy=memory,data-type=access-bandwidth,bandwidth=204800K \
  -numa hmat-lb,initiator=0,target=0,hierarchy=first-level,data-type=access-bandwidth,bandwidth=208896K \
  -numa hmat-lb,initiator=1,target=1,hierarchy=memory,data-type=access-bandwidth,bandwidth=204800K \
  -numa hmat-lb,initiator=1,target=1,hierarchy=first-level,data-type=access-bandwidth,bandwidth=208896K \
  -numa hmat-cache,node-id=0,size=10K,level=1,associativity=direct,policy=write-back,line=8 \
  -numa hmat-cache,node-id=1,size=10K,level=1,associativity=direct,policy=write-back,line=8 \
