wifi: iwlwifi: mvm: check n_ssids before accessing the ssids

Browse source

[ Upstream commit 60d62757df ]

In some versions of cfg80211, the ssids poinet might be a valid one even
though n_ssids is 0. Accessing the pointer in this case will cuase an
out-of-bound access. Fix this by checking n_ssids first.
