Added surface_vblanks list for safe destroy.

Added surface_vblanks list for safe destroy.

 - If an error occurs in tdm_client_display,
  it is a problem that cannot be recovered,
  but it should not affect rendering.
 - In this case, destroy tdm_client and stop using wait_vblank.
 - However, a problem occurs when accessing vblank after tdm_client_destroy.
 - Therefore, the created vblanks must be destroyed first and then
  destroy the tdm_client.
 - The added surface_vblanks list is to trace the created vblanks.
