Fix the compiler warning
drivers/char/agp/nvidia-agp.c: In function 'nvidia_tlbflush': drivers/char/agp/nvidia-agp.c:264:22: warning: variable 'temp' set but not used [-Wunused-but-set-variable] 264 | u32 wbc_reg, temp;
by marking the temp variable with __maybe_unused. The affected readl() is only required for flushing caches, but the returned value is not of interest.
v2: * declare temp as __maybe_unused (Helge)
