Fix GrGpuBuffer::onRelease() crash problem.
The crash is because method GrGpuBuffer::onRelease() is called on wrong
thread. SkMessageBus::Post(const Message& m) takes a const ref of the
message, so there is a little possibility the GPU thread received and
handled the message before SkMessageBus::Post() is returned. In that
case, the caller of SkMessageBus::Post() (AsyncReadResult) still holds
the last ref of the GrGpuBuffer, and then GrGpuBuffer() will just be
released on the wrong thread.
