r22838: Add in an explority test for what QFSINFO operations are valid on IPC$

It seems most opertaions are supported, but that the values are not
consistant.  I think these are very much hand-hacked stubs, which is
what they will be on Samba4 too.

I'll need to add some more 'don't fail for...' hacks before this
passes against Win2k3.
