iwlwifi: Fix softirq/hardirq disabling in iwl_pcie_gen2_enqueue_hcmd()

Analogically to what we did in 2800aadc18a6 ("iwlwifi: Fix softirq/hardirq
disabling in iwl_pcie_enqueue_hcmd()"), we must apply the same fix to
iwl_pcie_gen2_enqueue_hcmd(), as it's being called from exactly the same
contexts.
