What does this PR do / why do we need it:
When creating the new GKDropout, the original process used the Dropout's input's kernel_info to infer the kernel_info of new node. But if the input is a Tensor, then it hasn't kernel_info, which causes the GKDropout's input_kernel_info to be invalid.
In this submit, I manually set the kernel_infos to ensure they are always valid.

Which issue(s) this PR fixes:
Fixes #I3OW0G:[GraphKernel] Open GraphKernel in efficientnet, runtime_error
