[ Upstream commit f38a9774ddde9d79b3487dd888edd8b8623552af ]
when msdc_cmd_is_ready return fail, the req_timeout work has not been inited and cancel_delayed_work() will return false, then, the request return directly and never call mmc_request_done().
so need call mod_delayed_work() before msdc_cmd_is_ready()
