NTB: ntb_perf: Increased the number of message retries to 1000
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 Signed-off-by: Sanjay R Mehta <sanju.mehta@amd.com> Acked-by: Allen Hubbe <allenbh@gmail.com> Acked-by: Logan Gunthorpe <logang@deltatee.com> Acked-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
