xfree86: Remove device from inputInfo.devices if ActivateDevice failed.

Browse source 
After the call to xf86ActivateDevice, the new device will be added to
inputInfo.devices. However, if the subsequent call to ActivateDevice
fails, the correponding InputInfoRec for the device is deleted but an
entry still remains in inputInfo.devices. This might lead to a server
crash later on (on InitAndStartDevices for instance) when the device
control proc would be called for an invalid device.
