[dpdk-stable] [PATCH v2] app/testpmd: fix DCB set failure

When set DCB in testpmd, there is a segmentation fault. It is
because the local variable rss_conf in get_eth_dcb_conf()
is not cleared, so that the pointer member variable rss_key has
a random address, which leads to an error in the following
processing. This patch initialized the local variable rss_conf
to avoid this situation.
