It's important to get the initial size of cotables right because
otherwise every app needs to start with a synchronous cotable resize.

This has an measurable impact on system wide performance but is not
relevant for long running single full screen apps for which the cotable
resizes will happen early in the lifecycle and will continue running
just fine.

To eliminate the initial cotable resizes match the initial sizes to what
the userspace expects. The actual result of the patch is simply setting
the initial size of two of the cotables to a size that will align them
to two pages instead of one.

For a piglit run, before:
name               |  total |  per frame | per sec
vmw_cotable_resize |   1405 |       0.12 |    1.58
vmw_execbuf_ioctl  | 290805 |      25.43 |  326.05

After:
name               |  total |  per frame | per sec
vmw_cotable_resize |      4 |       0.00 |    0.00
vmw_execbuf_ioctl  | 281673 |      25.10 |  274.68
