numa: Avoid qerror_report_err() outside QMP command handlers

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP.  It should not be used
elsewhere.  Replace by error_report_err() in initial startup helper
numa_init_func() and board setup helper
memory_region_allocate_system_memory().
