[PATCH v2 3/3] mm/hugetlb: fix various coding style warnings.

[Christos Skarlos <christosskarlos.kernel@gmail.com>]

Resolve coding style issues flagged by the checkpatch.pl script. Specifically:
- Fix block comment formatting to keep trailing '*/' on a separate line.
- Add missing blank lines after variable declarations.
- Remove unnecessary braces {} from single statement blocks.

No functional changes are introduced.
