Windows: revise NTSTATUS response for ALLBUSY, ALLOFFLINE, and ALLDOWN

Replace STATUS_IO_TIMEOUT with RPC_NT_SERVER_TOO_BUSY for CM_ERROR_ALLBUSY.

Replace STATUS_PATH_NOT_FOUND with RPC_NT_SERVER_UNAVAILABLE for
CM_ERROR_ALLOFFLINE and CM_ERROR_ALLBUSY.

These errors provide a more meaningful message to end users when
a failure occurs.
