When set DCB in testpmd by clang, 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 random address.
