Windows: If no inlinebulkstat, set the flag correctly
If RXAFS_InlineBulkStatus fails with RXGEN_OPCODE,
cm_SetServerNoInlineBulk must be called with the 'no' parameter
set to True. Otherwise, thE cm_server object will not remember
that the RPc is not supported.
This is important for avoiding unnecessary timeouts on IBM AFS 3.6
servers.
