iwlwifi: dbg_ini: properly handle ini user trigger

in case of a user trigger while ini is enable we change
FW_DBG_TRIGGER_USER to IWL_FW_TRIGGER_ID_USER_TRIGGER in
iwl_fw_dbg_collect and then again we attempt to do so in
_iwl_fw_error_ini_dump which causes to abort the dump.

Fix it by removing the second check in _iwl_fw_error_ini_dump.
