Revert context lost expectations

Revert context lost expectations

After https://codereview.chromium.org/935193002 landed, the
GpuCrash.GPUProcessCrashesExactlyOnce should be passing again.

Revert https://codereview.chromium.org/928453002 that added these
expectations. As http://crbug.com/392891 is already fixed, remove that
expectation as well.

kbr: With the swarming changes removing the gpu tryservers, I'm a little
confused which bots I should try to verify that these gpu-related expectations
are actually cleaned up.

Sorry for the confusion. It's now mac_chromium_rel_ng, link_chromium_rel_ng and
win_chromium_rel_ng. I'll update the GPU bot documentation.

LGTM if the tests are now green.
