Lukas Wunner 575fe08c22 wifi: iwlwifi: mld: Restart firmware on iwl_mld_no_wowlan_resume() error 
Commit 44605365f935 ("iwlwifi: mld: fix building with CONFIG_PM_SLEEP
disabled") sought to fix build breakage, but inadvertently introduced
a new issue:

iwl_mld_mac80211_start() no longer calls iwl_mld_start_fw() after having
called iwl_mld_stop_fw() in the error path of iwl_mld_no_wowlan_resume().

Fix it.
