The damage-handler code now invokes dma_buf_{begin,end}_access()
for imported buffers. These calls were missing from the page-flip
and modesetting code paths. The patch also fixes an bug in the
original where an error code was overwritten by the result of
dma_buf_end_cpu_access().
v2:
* only return an error code from dma_buf_end_cpu_access() if
no other error code has been set before
