google/chromeos: guard cbmem_find() in verstage and bootblock
When vboot_handoff_flag() is called in the bootblock or a separate
verstage there's no memory nor the possibility of dram coming online.
Therefore, don't bother to attempt call cbmem_find().
BUG=chrome-os-partner:44827
BRANCH=glados
TEST=Built chell with separate verstage which pulls in vboot_common.c
dependency. No more linking errors w/ cbmem_find() not being
around.
