mm/hugetlb: enforce brace style

Documentation/process/coding-style.rst explicitly notes that if only one
branch of a conditional statement is a single statement, braces should be
used in both branches.  Enforce this in mm/hugetlb.c.

While add it, fix the indentation for vma_end_reservation.

No functional change intended.
