iwlwifi: mvm: don't call iwl_mvm_free_inactive_queue() under RCU

commit fbb1461ad1d6eacca9beb69a2f3ce1b5398d399b upstream.

iwl_mvm_free_inactive_queue() will sleep in synchronize_net() under
some circumstances, so don't call it under RCU. There doesn't appear
to be a need for RCU protection around this particular call.
