[Mesa-dev] [PATCH] i965: Solve Android native fence fd double close issue

[Randy Xu]

The Android native fence in i965 driver has two fd, one is from
App and stored in _EGLSync.SyncFd; Another one brw_fence->sync_fd
should be the dup of the first one, not direct copy.
These two fds are closed in dri2_egl_unref_sync in sequence.

Test: Run Vulkan and GLES stress test and no crash.
