Decrements the memory object reference count.
cl_int clReleaseMemObject(cl_mem memobj);
After the memobj reference count becomes zero and commands queued for execution on a command-queue(s) that use memobj have finished, the memory object is deleted. If memobj is a buffer object, memobj cannot be deleted until all sub-buffer objects associated with memobj are deleted.
Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns one of the following errors:
CL_INVALID_MEM_OBJECT if memobj is a not a valid memory object.
CL_OUT_OF_RESOURCES if there is a failure to allocate resources required by the OpenCL implementation on the device.
CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the OpenCL implementation on the host.
