[PATCH v2] iwlwifi: mvm: Fix an error handling path in 'iwl_mvm_wowlan_config_key_params()'

[Christophe JAILLET]

If the 'cmd_ver' check fails, we must release some memory as already done
in all the other error handling paths of this function.

Fixes: 9e3c39361a30 ("iwlwifi: mvm: support new KEK KCK api")
