Alexey Makhalov caea56d1f8 relocator: Protect grub_relocator_alloc_chunk_addr() input args against integer underflow/overflow 
Use arithmetic macros from safemath.h to accomplish it. In this commit,
I didn't want to be too paranoid to check every possible math equation
for overflow/underflow. Only obvious places (with non zero chance of
overflow/underflow) were refactored.
