radix tree test suite: Reduce kernel.h
Many of the definitions in the radix-tree kernel.h are redundant with others in tools/include, or are no longer used, such as panic(). Move the definition of __init to init.h and in_interrupt() to preempt.h Signed-off-by: Matthew Wilcox <mawilcox@microsoft.com>
