Windows: NPGetConnectionPerformance

Restore the implementation of NPGetConnectionPerformance
in AFSRDFSProvider.dll.  This time just return 0 for all fields
except for the preferred read/write size which is set to 64K.

When this function is not implemented at all, a query for
performance of a \\AFS path will be processed by the SMB
redirector.  This can result in a 20 second timeout while waiting
for the SMB Browser query for "AFS <20>" to complete.
