Subject: [PATCH] mmc: mediatek: fix cannot receive new request when msdc_cmd_is_ready fail
Git-commit: f38a9774ddde9d79b3487dd888edd8b8623552af
Patch-mainline: v4.20-rc1
References: bsc#1051510

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()
