ext4: Initialize the new group descriptor when resizing the filesystem

(cherry picked from commit fdff73f094e7220602cc3f8959c7230517976412)

Make sure all of the fields of the group descriptor are properly
initialized.  Previously, we allowed bg_flags field to be contain
random garbage, which could trigger non-deterministic behavior,
including a kernel OOPS.
