i965: Allocate shadow batches to explicitly be the BO size.
This unfortunately makes it malloc/realloc on every new batch, rather than once at startup. But it ensures that the shadow buffer's size will absolutely match the BO size. Otherwise, as we tune BATCH_SZ/STATE_SZ or bufmgr cache bucket sizes, we may get a BO size that's rounded up, and fail to allocate the shadow buffer large enough. This doesn't fix any bugs today, as BATCH_SZ/STATE_SZ are the size of a cache bucket, but it's better to be safe than sorry.
