commit 0712b5507866d6b3c900623eb1f81fffaec80ae2

mount: fix mount fail that caused by uninitialized struct
From: "Jianhong.Yin" <yin-jianhong@163.com>
recent changes of utils/mount cause a regression mount fail:
https://bugzilla.redhat.com/show_bug.cgi?id=1415024
can not reproduce it on x86_64(gcc on x86_64 might do struct
initialize by default, I'm not sure). but it can be reproduced
always on platform ppc64le aarch64.
