consolidate all mutux opertion
replace all pthread_mutex_lock/unlock to be svm_queue_lock/unlock So there all operation is based on defined mutux, and it can help us to debug or replace mutux locking method Change-Id: I9aeeb03bbbbf3d7a824c06a535e5d6a6b463b42c Signed-off-by: Ping Yu <ping.yu@intel.com>
