Subject: hugetlb: remove redundant validation in has_same_uncharge_info()

The callers of has_same_uncharge_info() has accessed the original
file_region and new file_region, and they are impossible to be NULL now. 
So we can remove the file_region validation in has_same_uncharge_info() to
simplify the code.
