fabtests/benchmark_shared: bandwidth_rma: force sync after each warmup iteration

Modify bandwidth_rma() to synchronize after every warmup iteration
instead of only at window boundaries. This ensures proper warmup of
the server->client connection path for unidirectinal mode

The writedata test asymmetry (client sends many writes, server replies
with single send per window) means only the client->server path gets
warmed up during normal iterations. Forcing sync during warmup ensures
both directions are properly established before timing begins.
