[PATCH 5/7] agp/nvidia: Ignore value returned by readl()

[Thomas Zimmermann <tzimmermann@xxxxxxx>]

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 removing the unused variable. The affected readl() is only
required for flushing caches, but the returned value is not of
interest.
