[PATCH -next] drm/mga: remove set but not used variable 'buf_priv'

[PATCH -next] drm/mga: remove set but not used variable 'buf_priv'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/mga/mga_state.c: In function 'mga_dma_iload':
drivers/gpu/drm/mga/mga_state.c:945:22: warning:
 variable 'buf_priv' set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
