[PATCH] drm/vmwgfx: remove set but not used variable 'srf'

[zhengbin]

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

drivers/gpu/drm/vmwgfx/vmwgfx_surface.c: In function vmw_hw_surface_destroy:
drivers/gpu/drm/vmwgfx/vmwgfx_surface.c:335:22: warning: variable srf set but not used [-Wunused-but-set-variable]

It is introduced by commit 543831cfc976 ("drm/vmwgfx:
Break out surface and context management to separate files"),
but never used, so remove it.
