[PATCH] drm/vmwgfx: Fix potential memory leak in vmw_fifo_create()

[Abdun Nihaal]

The memory allocated for fifo and fifo->static_buffer is not freed on
one of the error paths. Fix that by freeing them.

Fixes: c451af78f301 ("drm/vmwgfx: Fail to initialize on broken configs")

Compile tested only. Found using static analysis.
