test_rhashtable: remove initdata annotation

kbuild test robot reported a section mismatch warning w. gcc 4.x:
WARNING: lib/test_rhashtable.o(.text+0x139e):
Section mismatch in reference from the function rhltable_insert.clone.3() to the variable .init.data:rhlt

so remove this annotation.

---
I don't see this warning with same .config and gcc 6.3.x; however the annotation isn't essential so just remove it.
