[PATCH v2] memblock tests: compiling error

[Liu Xinpeng]

memblock.o: In function `memblock_find_in_range.constprop.9':
memblock.c:(.text+0x4651): undefined reference to `pr_warn_ratelimited'
memblock.o: In function `memblock_mark_mirror':
memblock.c:(.text+0x7171): undefined reference to `mirrored_kernelcore'

Fixs: commit 902c2d91582 ("memblock: Disable mirror feature if kernelcore
is not specified") and commit 14d9a675fd0 ("mm: Ratelimited mirrored memory
related warning")
