while waiting for the peer ntb_perf to initialize scratchpad
registers, local side ntb_perf might have already exhausted the
maximum number of retries which is currently set to 500. To avoid
this and to give little more time to the peer ntb_perf for scratchpad
initialization, increased the number of retries to 1000
