Fixed two -Wunused-but-set-variable warnings:

/arm/linux/display/aosp-4.14-drm-next/drivers/gpu/drm/arm/display/komeda/komeda_kms.c: In function ‘komeda_crtc_normalize_zpos’:
/arm/linux/display/aosp-4.14-drm-next/drivers/gpu/drm/arm/display/komeda/komeda_kms.c:150:26: warning: variable ‘fb’ set but not used [-Wunused-but-set-variable]
  struct drm_framebuffer *fb;
                          ^~
