[PATCH 2/2] app/dma-perf: fix infinite loop

[Dengdui Huang <huangdengdui@huawei.com>]

When a core that is not used by the rte is specified in the config
for testing, the problem of infinite loop occurs. The root cause
is that the program waits for the completion of the test task when
the test worker fails to be started on the lcore. This patch fix it.
