trace: init mutex before attempting to lock it
Call pthread_mutex_init before any calls to pthread_mutex_lock.
va_TraceInit(...) calls start_tracing2log_file(...) which
calls pthread_mutex_lock on the pva_trace->resource_mutex.
Thus, we need to ensure the mutex is initialized properly via
pthread_mutex_init before attempting to lock it.
