[PATCH] ext4: Don't warn about mnt_count after the first mount of a new mkfsed volume.

[PATCH] ext4: Don't warn about mnt_count after the first mount of a new mkfsed volume.

[Tao Ma]

From: Tao Ma <boyu.mt@taobao.com>

Currently, if we mkfs a new ext4 volume and mount it for the first time,
we will get the warning in the message like
warning: maximal mount count reached, running e2fsck is recommended

It is really misleading. So change the check so that it wouldn't warn in that case.
