gpudev: remove unnecessary memory barrier

Remove unnecessary rte_gpu_wmb from rte_gpu_comm_populate_list_pkts.
It causes a performance degradation in case of NVIDIA GPU V100.

This change doesn't affect any functionality as the status resides
in CPU registered memory.

Fixes: c7ebd65c1372 ("gpudev: add communication list")
