include/linux/hugetlb.h: is_file_hugepages() can be boolean
Make is_file_hugepages() return bool to improve readability due to this
particular function only using either one or zero as its return value.
This patch also removed the if condition to make is_file_hugepages
return directly.
No functional change.
