Subject: [PATCH] net/qede: fix possible null pointer dereference

[ upstream commit ef86e67ad5d873573882e19d92a206a842d22927 ]

In function qede_rss_reta_update(), the pointer params returned from
call to function rte_zmalloc() may be NULL and will be dereferenced.
So, should judge if the params is NULL or not.

Fixes: 8b3ee85efe11 ("net/qede: fix RSS table entries for 100G adapter")
