[v2] app/test: fix PMD perf test on devices with no socket ID
Checks
Commit Message
If the socket ID of a device is unknown, rte_eth_dev_socket_id(portid)
now returns -1 instead of 0 since commit 7dcd73e37965 ("drivers/bus: set
device NUMA node to unknown by default").
This change breaks the pmd_perf test on environment where the device
socket ID is unknown. The test fails with the following error, because
it does not find a lcore on socket -1:
> No avail lcore to run test
Take the new behavior in account in the pmd_perf test: in this
environment, the test can now run on any lcore, and not only those from
socket 0 (this was the old behavior).
