[PATCH] hash: fix segfault by adding param name NULL check

[Conor Fogarty <conor.fogarty@intel.com>]

Add NULL pointer check to params->name, which is later
copied into the hash datastructure. Without this check
the code segfaults on the strlcpy() of a NULL pointer.

Fixes: 48a399119619 ("hash: replace with cuckoo hash implementation")
