[dpdk-dev] [PATCH] examples/rxtx_callbacks: fix HW timestamp enable

[Harman Kalra]

Offloafing Rx timestamp is a device capability than queue capability.
Hence the logic to enable HW timestamp via DEV_RX_OFFLOAD_TIMESTAMP
flag should be before device configuration.

Fixes: cd1dadeb9b2a ("examples/rxtx_callbacks: support HW timestamp")
