XFS_IOC_SET_RESBLKS and quota

[Andi Kleen <ak@xxxxxxx>]

The interaction between XFS_IOC_SET_RESBLKS and quotas seems to be very 
strange. It doesn't check the current user quota when allowing reserves
(so you can set arbitarily high values), but when you try to write to the
reserved file after the big reservation it doesn't allow any writes even
when the user is really not out of quota.
