Avoid GetState IPC call during AllocateRingbuffer.

Avoid GetState IPC call during AllocateRingbuffer.

SetGetBuffer(id) resets get and put offsets to 0.
So no need to ask CommandBuffer::State through GetState() IPC call.

CreateTransferBuffer() allocates new cmd buffer of size 1MB.
No need to check for num_entries after new allocation of ring_buffer, as always state.num_entries==num_ring_buffer_entries after this new allocation.

PTAL.

The patch is good.
However, it doesn't look like you have been added to the Corporate Contributor
License Agreement submitted by Samsung, which explicitly names which of their
employees is allowed to contribute to Chromium.
Could you ask to be added to the CLA? Or let me know if you already have been
added, but the information may be out of date.

I have asked Laszlo to add my name to CLA. 
One more /proc/cpuinfo patch is also pending on CLA.

I will update here once CLA is done.
