Subject: [PATCH v3 4/5] ntb_perf: increase sleep time from one milli sec to one sec

After trying to send commands for a maximum of MSG_TRIES
re-tries, link-up fails due to short sleep time(1ms) between
re-tries. Hence increasing the sleep time to one second providing
sufficient time for perf link-up.
