MAXQUOTAS value defines maximum number of quota types VFS supports. This
isn't necessarily the number of types ext3 supports and with addition of
project quotas these two numbers stop matching. So make ext3 use its
private definition.

MAXQUOTAS value defines maximum number of quota types VFS supports.
This isn't necessarily the number of types ext4 supports. Although ext4
will support project quotas, use ext4 private definition for consistency
with other filesystems.

MAXQUOTAS value defines maximum number of quota types VFS supports.
This isn't necessarily the number of types reiserfs supports and with
addition of project quotas these two numbers stop matching. So make
reiserfs use its private definition.

MAXQUOTAS value defines maximum number of quota types VFS supports.
This isn't necessarily the number of types gfs2 supports and with
addition of project quotas these two numbers stop matching. So make gfs2
use its private definition.

This isn't necessarily the number of types ocfs2 supports and with
