[PATCH] video/fbdev/core: Mark debug-only variable as __maybe_unused

Compiling fbcon.c gives

../drivers/video/fbdev/core/fbcon.c: In function 'fbcon_exit':
../drivers/video/fbdev/core/fbcon.c:3358:7: warning: variable 'pending' set but not used [-Wunused-but-set-variable]
 3358 |   int pending = 0;
      |       ^~~~~~~

The variable pending is only used for fbcon debugging. It's unused
otherwise. Mark it accordingly.
