  [WebGPU] RemoteBufferProxy::mapAsync does not call completion handler when the call fails

Reviewed by Myles C. Maxfield.

GPUBuffer.mapAsync returns Promise<undefined>, so we can't return a
GPUError, but we still need to call the completion handler.

Discovered running the conformance test suite.

* Source/WebKit/WebProcess/GPU/graphics/WebGPU/RemoteBufferProxy.cpp:
(WebKit::WebGPU::RemoteBufferProxy::mapAsync):
Call the completion handler.
