[PATCH v2 3/4] lib/rhashtable: Replace kernel.h with the necessary inclusions

[Andy Shevchenko]

When kernel.h is used in the headers it adds a lot into dependency hell,
especially when there are circular dependencies are involved.

Replace kernel.h inclusion with the list of what is really being used.
