Xi: if XTEST device creation fails, fail the master devices.

Browse Source 
When getting close to the MAXDEVICES limit, the creation of XTEST devices
may fail due to device id exhaustion. In that case, fail the creation of
master devices too and return an error to the client.

Theoretically, we could alloc the MDs without the XTEST devices but that
will get interesting when a client starts sending XTEST events through those
devices.
