block: bump coroutine pool size for drives
When a BlockDriverState is associated with a storage controller DeviceState we expect guest I/O. Use this opportunity to bump the coroutine pool size by 64. This patch ensures that the coroutine pool size scales with the number of drives attached to the guest. It should increase coroutine pool usage (which makes qemu_coroutine_create() fast) without hogging too much memory when fewer drives are attached.
