SWDEV-196326 - [hipclang-vdi-rocm]: [FBA-80]: Runtime error when all GPUs are hidden by ROCR_VISIBLE_DEVICES
	 - Adjusted hipGetDeviceCount to return "hipErrorNoDevice".
	 - This was done to match the same behaviour as HIP-HCC, and API spec for when no devices are found. Rather then return "count = 0" as it did.
