[PATCH 10/45] iwlwifi: mvm: check iwl_mvm_wowlan_config_key_params() return value

[Emmanuel Grumbach <emmanuel.grumbach@intel.com>]

From: Eliad Peller <eliad@wizery.com>

commit 9a4c830007817e ("iwlwifi: mvm: refactor d3 key
update functions") refactored some code into
iwl_mvm_wowlan_config_key_params() function, but the
return value was never checked, and not all the function
flows returned valid values. fix it.
