Ensure that the mount command shows "with quotas" when quotas are enabled.
When quotas are enabled with the quotaon(8) command, it sets the
MNT_QUOTA flag in the mount structure mnt_flag field. The mount
structure holds a cached copy of the filesystem statfs structure
in mnt_stat that includes a copy of the mnt_flag field in
mnt_stat.f_flags. The mnt_stat structure may not be updated for
hours. Since the mount command requests mount details using the
MNT_NOWAIT option, it gets the mount's mnt_stat statfs structure
whose f_flags field does not yet show the MNT_QUOTA flag being set
in mnt_flag.
The fix is to have quotaon(8) set the MNT_QUOTA flag in both mnt_flag
and in mnt_stat.f_flags so that it will be immediately visible to
callers of statfs(2).
