ocfs2: Avoid unnecessary block mapping when refreshing quota info
The position of global quota file info does not change. So we do not have to do logical -> physical block translation every time we reread it from disk. Thus we can also avoid taking ip_alloc_sem. Acked-by: Joel Becker <Joel.Becker@oracle.com> Signed-off-by: Jan Kara <jack@suse.cz>
