drm/i915/fence: Mark debug_fence_init_onstack() with __maybe_unused

BugLink: https://bugs.launchpad.net/bugs/2085849

[ Upstream commit fcd9e8afd546f6ced378d078345a89bf346d065e ]

When debug_fence_init_onstack() is unused (CONFIG_DRM_I915_SELFTEST=n),
it prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:

.../i915_sw_fence.c:97:20: error: unused function 'debug_fence_init_onstack' [-Werror,-Wunused-function]
   97 | static inline void debug_fence_init_onstack(struct i915_sw_fence *fence)
      |                    ^~~~~~~~~~~~~~~~~~~~~~~~

Fix this by marking debug_fence_init_onstack() with __maybe_unused.

See also commit 6863f5643d ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
