kernel: Only setup kernel context globals once
The globals setup by the function calls when creating a new kernel
context only need to be setup once. Calling them multiple times may be
wasteful and has no apparent benefit.

Besides kernel users potentially creating multiple contexts, this change
may also be useful for tests creating multiple setups.
