sched/fair: Mark m*_vruntime() with __maybe_unused
When max_vruntime() is unused, it prevents kernel builds with clang,
`make W=1` and CONFIG_WERROR=y:
kernel/sched/fair.c:526:19: error: unused function 'max_vruntime' [-Werror,-Wunused-function]
526 | static inline u64 max_vruntime(u64 max_vruntime, u64 vruntime)
| ^~~~~~~~~~~~
Fix this by marking them with __maybe_unused (all cases for the sake of
symmetry).
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
